Hi MindSet,

re:
> Might there be some way to merge groups?

The Ungroup function can be used to merge groups if you have sub objects selected when you trigger it. It will merge the contents of the sub group up into the parent.

So for example if you have 2 groups "GroupA" and "GroupB" and you want to merge the contents of GroupB into GroupA.

Select GroupB, then click on GroupA's name and choose "Assign selection here" (or right click on it which is a shortcut for assign)

Select GroupB which is now a child of GroupA and use "Ungroup". The contents of GroupB will be merged up into GroupA and the now empty GroupB will be removed.
