Exporting characters and importing them in a new campaign (and back again into the saved old one) is the number one thing on my list. The only other things I can think of would be the ability to delete "saved/exported creatures", to be able to "watch combat as if participating" and the ability to posses one creature without also having to play all other "enemies" during combat.
For everything else I unfortunately do have to say: use the editor, and I do think that's where most of the things I see requested on these forums and elsewhere actually do belong.
The editor is a lot less harder to use than one might think and the community is providing a lot of tutorials that are very helpfull.
I most certainly don't think one can blame Larian for lack of transarency as they have been very open about what the GM Mode would be like, what it could do and what it couldn't.
