A while ago the dev posted somewhere saying that he would make them keyswitchable, but then kind of vanished.
Well, he's back, and from the looks of the GUI (I'm at work so no time to listen to the demos or try it out), he's delivered something special -- it looks really intuitive and powerful.

Can't wait to have a play.
I've no ties to the dev other than being a customer.
