It would be nice to have some kind of version history for a page.
So that you can see who changed what and that you can go back in history to an earlier version if you are not happy with the current page.
For rsc's, this is quite easy to do, even in a module. Managing the edge administration is a bit more challenging though...
That would be a REALLY good feature to have; I am almost inclined to say, that's a must. Even simple wiki's have it.
Fixed dbe1637 (only resources, not edges).
