Split lets you split your screen into two vertical panels. You are able to view the same page side by side which comes in handy when you want to compare content, translate content and so on.
Click on the Split Screen icon in your browser bar. You now have 2 panels.
Click a second time and it will revert back to single panel mode.
NOTE: This extension will not work on all pages as it uses framesets and for security reasons, some websites understandingly prohibit this.
