MIDI File Association
Certainly not a show-stopper, and easily gotten around, but...
Do any of your programmers care to take the time to let file associations "pass through" the Command Center?
Viz.: If I start Sonar on it's own, and create a MIDI file with something else and double-click it (actually, the program I use uses Process.Start(<ProcessStartInfo>), but...same thing essentially), Sonar automatically opens the file because .MID is associated with it.
However, if Sonar was started via the Command Center, this doesn't happen. Double-clicking the MIDI file doesn't do anything. Or anything I can see, anyway. It certainly doesn't show up in Sonar. ;)
This is really a minor, minor thing. But it would be convenient. :)
