This isn't a deal killer, but it would be nice to see the WAV being created as I record (the way you can in most other DAW apps.) I don't know how many times I've played through a long sequence only to learn that my signal was not being captured for some reason. If I didn't already have the expectation of seeing a flat line while recording, this would be caught immediately.

(I'm still using 2009.5... for all I know this might already be fixed in 2010)

Mostly because of this one thing, I usually record in Sonar, not in RB
