Is the editor going to be a frozen version from when the EE was being developed?
Or will it include some of the newer features like the snazzy new dialog editor and stuff like terrain undo, assuming you got around to adding that?.
Another thing before I forget: Awhile back Raze mentioned that some changes to the workshop make it possible for larger Steam Workshop file sizes. The old version had a 100mb limit which was way too small. I actually had to cut stuff out of my mod to make it fit.
