Maya’s Selection Sets are extremely useful in managing your scene for those often selected objects… But they can start to be a little tough to manage..
I originally found this tool on http://www.creativecrash.com!
I found it very useful but I wanted more…. So a long while back I dove into the MEL code and added more! 😀 It has been a long time since I have looked at the code but found I use the tool a lot still to this day!
