First of all, thanks for this amazing app. The ability to put together chord charts while away from a computer is a game changer for me. I do, however, have a feature request:

It would be great to have to ability to play a chord back while in edit mode. The purpose of this is let you hear the chord you just entered so you can determine if its the chord you want (or though you heard in your head). Since I'm usually using this app while I am away from a keyboard, it would be nice to be able to ear-check a particular chord with out having to get out of edit mode and go into playback mode (which really slows me down when I'm trying to document a song quickly before rehearsal). You could have a button right next to the chord input button which, when pressed, plays a chord.

If this feature is already there, please forgive me, for I'm new to this tool. Once again, this is an amazing tool.
