Hey mate, nice add-on! I got the hint in the Git for Simple Tab Groups (https://github.com/drive4ik/simple-tab-groups) from an other user while asking there for a feature doing what your add-on is doing! .. and now: tataa, my problem is solved. And what i real like is the quick change of the options in the menue ... this add-on has all i need ... btw. i realy love the design! ;-) ... its a litte "ghostery "-like :-D ..
