I would like to see camera angles in editor mode. It is hard to place objects inside buildings at the moment. The in game editor feature is good however I was able to change objects in FCS-R however unable to see how I can do that in GG.
A clean entity/object list in in game editor mode would remove the need to add camera angles.
For in game editor mode:
Easily chose from the list of entities you have.
Easily place the item and select the where it should go. If you want to put something on a table it can be a little tricky.
Those are the only things I can think of for now.
