I have been experimenting with the global variables in the constraint manager. I must say that I find this tool very valuable and truly believe that it will be a great time saver for those who use the constraint manager a lot.
There is one thing that I think that would make it more user-friendly. That is if we could select the variable number from the list and copy it to the clipboard (ctrl+C), then paste it when editing the existing constraints. (Ctrl+v) This would help a lot when editing constraints that have been set by someone else or even myself. Rather than having to toggle back and forth to see which one to use. and then type the variable number. But of course, I am working with limited brain cells these days.

Thanks again for all of the hard work you guys do for us.
Scott.
