Rated 4 out of 5 stars

I like the idea of this extension. On Linux some buttons already have icons - so for consistency I though this looked like a cute idea.

Unfortunately it seams to conflict with any button that had a icon already - nothing gets shown. Which destroys the effect.

Otherwise well done :)

This review is for a previous version of the add-on (0.1.2). 

v0.1.4

i added some of the missing ones, but it might be awhile before i do the rest as i have to go through and check each button
