Plz add a function to right click the icon to move to the start of the tab list.
Then it will be wonderful :)

This review is for a previous version of the add-on (0.2.1-signed). 

New version (0.4)

I've implemented what you asked for, thanks for your review!

You can now move the tab to the beginning (after the pinned tabs) or to the end of the tab list.

Also, you may use "accel-alt-home" (for beginning of tab list) and "accel-alt-end" (for end of tab list) keyboard shortcuts, with "accel" being either "ctrl" (on windows/linux) or "command" (on mac).

Enjoy!
