In the ProChannel the interface is well designed. It's easy to see anything is on or off.  On the power button is blue.  Off it's gray.
 
An example where this doesn't happen is AudioSnap.  On/Off is very hard to tell.  I never can remember, especially just objectively intuitively trying to guess which shade of white means on or off.
 
It's a simple request, just hoping for X4 the bakers take that idea as a helpful QA/feedback point.

I agree, a simple color issue. Haven't checked out audiosnap in platinum yet, but I always thought the dark grey to light grey on/off switch there was too subtle. There were plenty of times I wouldn't have worked with AudioSnap for a while and come back to it, look at it and press the power button not sure if it was on because it was light grey and not blue or orange or green.
