Thank you for checking out.
This extension is focus to only one function; "Save tab sets to Pinboard".
Pinboard extension by mceglowski is great but mainly I use the save tab button.
And I wanted to finish the job in one click.
So I made this extension.
If you click on the icon, it direct you to save tab set page.
This also adds context menu so you can right click anywhere and choose "save tabs to Pinboard" to do the same.
In this case you can hide the icon without losing its functionality.
