I didn’t think so from looking at some initial data I had just skimmed over and half ass looked at before joining the party here, but I figured I would ask just in case.
It's actually a current debate. Some want editing abilities, others don't. It would require some significant programming changes, and the agreement and cooperation of many developers, so I'm not counting on it even though I'm in the pro-editing camp.
