Moving a group in another one

[LuposX]

If you have a group and accidentally move it above another group, the elements in the group get messed up (they will be all in the group that got moved), maybe don't let groups overlaps? So that this mess doesnt happen.

I think nested/grouped nodes would solve this issue. I really wish it was possible to make grouped nodes the way blender does it.
