Midi note names - would anyone use this?

Cubase and to a lesser extent Reaper/Live have a function which shows the midi notes name on that note. So C3 would have a label on it saying C3.

Poor example, but shows the general idea: http://emusician.com/onli...sive/cubase_5_figA.jpg


Would anyone else find that useful? I know Sonar's visual feedback is pretty good but having the note name shown can be useful at times.
