This may already exist in Sonar, but I haven't found it in several years ...
In PRV, would it be possible to rename the tabs. This would be especially when you have multiple tracks; if you have just one track in a PRV tab, that's fine - the instrument is named. As soon as you add another track for the window, the tab just says "Piano Roll - Multiple Tracks." It would be nice to rename this "drums" (where there may be two or three tracks of bass drum, snare, cymbals, etc) or "percussion" or "horns" .. etc.
Also - could the tabs be rearranged (by dragging), including the console view tab?
Cheers
