Nice! This is good, this is good... And in fact this should have been how it is implemented!
Only request for succeeding versions, is it possible to automatically "collapse" or "hide" this addon bar after a certain amount of time (Say, three seconds)? Then the arrow will remain to toggle the bar on again.
Thank you for your review. As for your idea - I may do it in one of future releases. The only problem is that some extensions use add-on bar to indicate status or internal events - you won't see this if you hide the bar. I'll think of it.
