Rather than make a whole new editor, I would say just build upon the existing Rig Manger and include the above features. It already has the basis of being a very powerful tool in its current state.
While I definitely like the ability to tweak at will on the unit itself (and Kemper has done a fantastic job of putting the "key" knobs and adjustments on the front panel), there are times when all I want to do it nudge something just 0.10 of a number and doing that with the knobs is a bit difficult sometimes to get that fine of and adjustment with them. Doing that onscreen would be so much easier, not to mention naming profiles would be a piece of cake.
I give Kemper and the unit an A+ Grade otherwise. This unit is revolutionary, to say the least.
Gotta give the man an 20+++++ on this one!!! fjk1138 hit the nail on the head with a 20 lb sledgehammer.
I also agree that it's a remarkable piece of tech and ingenuity.
