I think You could set toolboxid attribute on TabsToolbar so it'll stay customizable outside toolbox.

And in the long run ... integrate groups with Tab Candy groups,

As mentioned in earlier review I love it.

This review is for a previous version of the add-on (0.6).  This user has a previous review of this add-on.

Super great idea

Thanks a lot for the tip, I've implemented this and it will be in version 0.7!
