when I was talking to WhiteTie 2 weeks ago there was a good reason for that function to be disabled but I can't remember it. I do know its not necessary to repack the theme into a zip after editing.
it’s my first time ,I was nervous when i start recording the screen i click anywhere and make mistake to repack the theme into a zip after editing ‘ i don’t know the reason for that function to be disabled but it’s cool to have it in reaper like in Nuendo
