The 'item' editor will seem to be allowing you to change races, but that only works for player races. The RPC race changing doesn't seem to work, though i dunno, because i haven't tried to edit any RPCs (I don't use them)
It was kinda fun to see what it would be like to have stuff like a second Boomerang Shurikan, or a Powerglove; or maybe start the game with a high-level Bishop, etc. I haven't counted any games i modified as finished, though.
The no-item editor is fine if you want to stipulate training, eg. you've done Stealth training the "hard" way so many times, you just take it as given, and move on.
