Better Text View

NEW CHANGES

New variables for reverse color hue correction.
Variable '--g_max_child' (default value was hardcoded as 4) sets maximum child elements a node should have to set its line height.
CSS Variables '--g_zoom_keycode' for setting 'Zoom' key and '--g_avoid_negative' that avoids flicker of "negative" images in reverse colors.
Changes to line height which applies to some paragraph elements, so that different paragraphs lines do not have very different spacing due to 2 different line heights applied.
Setting "--g_foot_re" in either custom CSS or global CSS rules will make footer areas of website colors as normal in reverse colors.
Zoom value can be given in custom CSS rules.
Setting Strength to -300 (minus 300) skips doing high contrast text changes totally, resulting in faster processing.
Global CSS rules which applies CSS rules to all sites not blacklisted.
New "high contrast dark mode" enabled text contrast method determines color brightnes of text and makes non-high contrast text black / white depending on Strength slider value. Increasing Slider towards 300 makes most text black (or white for reverse colors). Decreasing slider towards (and below) zero makes less of text black.
Input text elements with text will be increased in width (and height) proportional to text length or Font increase %. This effect can be disabled by enabling "Input border" and the "start 3" disabled and "skip links" enabled combination.
Changes to brightness calculation and "high contrast dark mode" which handles text contrast with new method. The "high contrast dark mode" works almost as fast as older method and depends on strength slider value approx. 100 to 300 for highest contrast.
New option in Reverse colors for processing Before / After pseudo elements' background images which are then correctly displayed.
New "Font name" setting makes all text of font type as specified in setting. For example, enter 'Sans-Serif' / 'Serif' / 'Monospace' in "Font name" text box and refresh page to get all text of that font type (or name).
Global settings are saved when exporting a whitelist to a file.
New option to Disable Better Text View on a site temporarily while keeping settings instead of deleting them (which blacklisting/disabling does).
Zoom % is now dynamically changed by adjusting Strength slider, without having to refresh the page.
Holding Shift key down and moving mouse over any text area will "ZOOM" the text in that area by 175% (or by Strength % if slider is not zero) when "Num Lock" key is on.
"Force max opacity" now changes background color of BODY element only if "Force Reverse colors" is enabled AND Skip Links is enabled + Start 3 disabled. Other effect of making text totally opaque does not depend on any other options.
31 Presets can be defined with custom settings of sliders and options. These presets can be loaded to quickly change the settings to particular configuration for a site.
In Dark mode and Reverse colors mode, the Brightness and Contrast sliders now update the colors while changing instead of requiring a refesh of webpage. This works in "Dark mode" and "Reverse colors" mode, but for normal pages there is no brightness / contrast change needed.
Strength slider controls the "text vs background contrast" with text color changed to black / white. Negative strength preserves original colors of site and high positive value create greater contrast. There are 2 calculation methods for contrast, the older method when "High contrast dark mode" is disabled and new method when it is enabled. Depending on website, either will work though new option is slightly faster.
Option "High contrast dark mode" makes greater background + text contrast when brighness / contrast slider values are changed in Dark mode. If enabled with/without dark mode, the newer text contrast method is used. If text contrast is not working as expected, try enabling / disabling this option to chamge between old / new method of text contrast.
New "colorblind adjusted colors" which changes colors of text to suit colorblind condition. In dark mode or reverse colors, the text hue is changed toward green color (since LCD screens display green color brightly) while in normal light theme, the text is changed for blue color.
Site theme computed Lightness value displayed in popup settings. A value greater than 0.5 considered as "Light theme" and below 0.5 as "Dark theme".
If strength is an ODD number, input textbox color is changed to black/white depending on its color.
"Skip text height changes" avoids changing font heights of text and INPUT elements like text boxes and select boxes.
New option to add custom CSS rules to the site
If either of "Dark mode" or "Reverse Colors" is enabled in global options, all websites colors are changed to "dark theme" colors. If the theme calculates "Lightness" wrong, then enable both "Reverse colors" and "Dark mode" to override the wrongly computed theme.
IMPORTANT: The browser's "Text Size" Setting SHOULD ALSO BE CHANGED TO "LARGE/VERY LARGE" or "16 px to 24 px". If its value is low, on some sites OVERLAPPING / HIDING of text columns can occur.
DO NOT ENABLE BOTH "Dark Mode" and "Force Reverse Colors" except to override theme colors. This condition is not considered and there will be problems in results.

VERY IMPORTANT WARNING: If you are COPY+PASTE-ing from a website which has been changed by this plugin, DISABLE the plugin for that site and THEN copy + paste. Otherwise a lot of styling changes will also get pasted which is not on the original site.
When using HTML Editors in software like Wordpress or similar, disable the plugin for that site to prevent styling changes from being entered in the HTML editor.
ALSO IF YOU TAKE A PRINTOUT OF WEBPAGE changed by this extension, IT MAY NOT PRINT CORRECTLY. SO KEEP THE "Disable for this site" option ENABLED when PRINTING.
DISABLE PLUGIN = Select "Disable Better Text View for this site" or "Disable Better Text View on this site temporarily (keep settings)" option on Options menu or DISABLE "Activate on all websites" in All Settings page, whichever is preferred.

DETAILS

The text size is increased inversely depending on its size. This means small sized text is made much bigger than larger text, which is slightly increased in size. All text within size of Threshold setting is increased in size with text closer to Font Threshold size increasing less than text much lower size than Threshold, depending of Font Increase % setting. Text size of ANY TEXT IS NOT DECREASED to less than its normal size. Smaller text becomes as large as (or larger than) text of Threshold size. Text near the Threshold size is unchanged or changed very slightly.
If "Activate on all websites" option is disabled only "whitelisted" sites are changed, else ALL sites get processed.
Frames inside of site are also processed, but their settings are of the origin site of the frame, which MAY NOT be the site displayed in address box.
Brightness and Contrast Slider controls the brightness / contrast of text/background with -200% to 400% and -100% to 300%.
The colors of text are changed for maximum contrast depending on value of "Strength" slider (unless "Avoid colorful text" is selected which skips "colorful" text,  and if "Skip white text" option is enabled, which skips WHITE text). If greater than 200, text colors change for maximum contrast.
Decreasing "Strength" setting to negative values like -120 or -250 can restore the original text colors of website instead of high contrast black / white text. A strength of -300 (negative 300) skips all high contrast changes and original colors are kept, and page processed faster.
If Strength is ODD value, and there are INPUT text boxes on site, the input text will be made black / white depending on color.
The "Font Weight" slider can be changed to lowest 100 (very thin) upto 900 (very thick / bold) text. This is useful for adjusting sites having very thin text or very bold and thick text. When "Start 3 letters bold" is enabled, (slider value + 400) is taken as weight of bold letters and normal text has weight of slider value, if slider is less than or equal to 400. For slider above 400, the slider value is taken as weight of 3 letters and all other text is normal.
Font name can make the font of most of text on a page the font specified.
Before a preset is made, select the preset number at the very start. Then make the customizations and finally click "Save" to save to a number between 1 to 31. This saved preset can be loaded by clicking "Load" after selecting the number of preset. Clicking "Refresh" button after all steps is recommended of knowing preset has been saved / loaded. Presets are stored in the "whitelist" list so exporting whitelist to a file will also save presets. Settings with a selected preset do not get automatically updated if a preset is changed. One has to "Load" the preset again.
ALL CAPITAL TEXT option makes all site text in capitals. It works on NON-ENGLISH languages too.
Starting 3 letters bold option makes all words first 3 letters bold and also works for NON-ENGLISH languages. If there are problems with some links or menus not working, enable "Skip links in 3 letters bold" option to avoid making links 3 letters bold.
If "High contrast dark mode" is enabled in Dark mode, then brightness and contrast values are applied without preserving image colors, and some images can get colors distorted.
The "Dark Mode" option is for black themes and, when enabled, allows increasing of Brightness (by the "Brightness" slider, range 0 to 300) and Contrast (by the "Contrast" slider, range 0 to 300) of text and background colors.
The "Force Reverse Colors" option allows site to "Reverse" colors, so that a light site becomes black. It is useful for changing colors of sites to "Dark Theme" or "Dark Reader" view while preserving (most of) images' colors. In case a webpage does not have its background color reversed, enabling "Force max opacity" will force a reversal of the BODY element background color (but only if "Start 3 disable / Skip links enable" is set). This may not work if background color is set by non-BODY element.
The "Invert Image Colors" option, which appears when "Force Reverse Colors" is enabled, causes images and videos colors to be inverted, so due to double inversion images and videos become normal. If it is disabled, the images and videos are not doubly inverted in color, causing them to look distorted in "reverse color".
"Reverse color hue correction" changes colors to look same as original website in reverse colors.
Option "Process :before/:after elements" in Reverse colors for processing Before / After pseudo elements' background images which are then correctly displayed (but only if "Invert image colors" is enabled). If any images in reverse colors are displayed in reverse colors, try enabling this option, with "Invert image colors" also enabled.
The text brightness (range -200% to 400%) and contrast (range -100% to 300%) can be changed by the sliders when "Reverse colors" is enabled. To revert to original brightness and contrast, set Brightness and Contrast to 100%.
The popup options show the "Lightness" value of current site. If less than 0.5, then it is considered "Dark themed", if more than 0.5, it is "Light themed". Dark themed site colors can be changed by "Dark mode" while "Light themed" site colors can be changed through "Reverse Colors". Some few sites may detect theme wrong, then enable BOTH Dark mode and Reverse colors to force site color changes.
The menu, large sections and Input elements of site are increased in size according to the Font Increase %. If there are problems in display of menus / header imaages or overlapping text columns, enable "Skip NAV & SECTION" checkbox. The "Skip NAV & SECTION" also skips applying Reverse Color to images inside NAV and HEADER elements, which are (usually) at top of website, when "Force Reverse colors" is enabled.
"Skip text height changes" will not change heights of text, and INPUT elements like text and select boxes.
Enabling "Apply custom CSS for site" will allow you to enter custom CSS rules for the site
The "Disable Better Text View on this site temporarily (keep settings)" option keeps settings saved while blacklisting (making no changes) the site. If the settings on a site need to be temporarily disabled, use this option insted of "Disable Better Text View on this site".
"Font name" option allows changing font of all text of page with the font entered in textbox. After putting font name in textbox, press Enter and the font will change immediately without requiring refresh of page.
The "inverse text size" font enlarging can be changed to "normal size" by changing font weight after setting enable "Skip links" and disable "Start 3 letters". This makes the "Font Weight" slider proportional to inverse text size calculations. 400 weight is default "inverted text size change" whose amount decreases at font weight of 300 .. 100 .. 900 .. 500 with 500 being "normal" website text with no "inverse text size change". If a site has VERY bad layout due to "inverted text sizing", decrease the font weight to 100 / 900 .. 500 which will keep original font size settings. Remember the setting switch (skip links: enable and start 3 letters: disable).
Global CSS Rules are applied to all sites before Custom CSS rules of a site. Change to some particular rules that need to apply every site.
Additional features are input box borders, underlining of links and saving/loading of settings whitelists/blacklists,
"Skip headings" does not process H1 to H4 HTML tags.
'Colorblind adjust colors' when enabled changes text colors and background to suit colorblind condition. In dark mode or reverse colors, the text hue is changed toward green color while in normal light theme, the text is changed for blue color.
The calculated website background colors are used to determine if site has "Light" theme (lightness greater than 0.5) or "Dark theme" (lightness less than 0.5).On some sites this calculation may result in wrong theme choice (light website calculated as "dark" theme or reverse).If this happens, override this value by setting both "Dark mode" and "Reverse Colors" to enabled.( This only applies if you want to keep a "Dark" mode or "Reverse colors" on the site).
VERY IMPORTANT WARNING: If you are COPY+PASTE-ing from a page which has been changed by this plugin, DISABLE the plugin for that site and THEN copy + paste. If you are editing or submitting HTML content online using a content management system like Wordpress or having an HTML Editor, DISABLE this extension for that particular site. Otherwise, the HTML will contain unwanted styling elements generated by the extension.
WHEM PRINTING A PAGE modified by this extension, KEEP "Disable for this site" enabled otherwise the PRINTING WON'T BE CORRECT.
