Another thing I'm interested in is making it easy to style the RTE--or, at the very least, to have two different styles of it, one dark-on-light and another light-on-dark. That was the reason that I looked into updating to CKEditor; a lot of people use our light-on-dark site scheme to ease eyestrain, and there have been complaints about the RTE still being dark-on-light even in that site scheme.
