Oh yeah, almost forgot, a really trivial modification that would save me a LOT of carpal tunnel angst:
Make the DOWN arrow key the 'decelerate' key (or just add it). Reaching over to hold down the '.' key whenever I want to decelerate gets kind of painful after a long session.
Or perhaps someone could just tell me how to re-arrange the keymaps in Trancendence? I didn't see an obvious file tile mess with.
