Selection Set

[hashman63]

Hi! Nice addon. I would suggest you to make a function to hide not selected sets. so not used controls rig, hid and do not interfere with the work of the animator. And I would also make the button color highlighting the active set. Now it is not very conveniently implemented multiselect function (you need to press/press the plus button). It will be much more convenient if the multiselect function will be realized with the Shift key. I hope you will appreciate this suggestion and make it in the next update.
