pinner

Download extension

adds a pin tab button so you don't have to right click to pin or unpin.This application puts a pin to the right of your address bar. Click it to pin or unpin a tab. This is useful to people who pin and unpin tabs a lot and hates the lengthy process of right clicking and finding the "pin tab" option.

You can also use the hotkey alt-p to pin/unpin a tab.
