Take a page from Cubase's book and have an option (or default) where each note in the piano roll of the MIDI Editor also displays it's note name. In dense parts or score, being able to quickly read where a "bad" note is or how the part is laid out in Piano Roll mode would make life SOOOOOOO much better for those of us writing music daily. Attached picture is low-res, but you get the idea.
