Agreed. This would be a very useful app for composing.

In the interim, try using the separate applet on the 2012 BiB CDROM. It's called Guitar Chord Dictionary. It installs to the desktop as a standalone app. If you have an idea of the root or a location on the guitar neck, it shows a bunch of decent grips with each note spelled out in a list and on the neck. It's a timesaver.
