this feature stop working long time ago since 1.6 i believe
very usefull one
but looks like for now abandoned alittle
I have used it some times, week ago, and it do select/deselect by mouseclick.
But the shift-variant or label-click i havent seen before so i have no idea what exactly should happen.
So i am using it beside AddonProfiles and both working great together.
But you could enlighten me up a bit, probably i could fix it then.
Whats about the owner of this addon ?
Already in there. Click on your first add-on and release the button. Then hold down the shift key and click on your last add-on. Everything between the two, inclusive, should then match the new state of the first add-on.
