I'd like to see a button that leads to some music theory aids, such as:

Circle/Wheel of 5ths.
Notes in Scales.
Notes in Chords.
What the 1, 2, 3 (I, II, III) etc. chords are in various keys.
What extensions are and do--possibly even in a particular chord.

More advanced:

Some cheat sheets on modes.
Info on modes in the various keys.
Rhythm, poly-rhythms, etc.

These can be as interactive as possible (keyed to the Key or chord entered), but just the presence of simple "cheat sheets" would be a useful addition and keep everything handy, as well as be educational.

I wrote a lot of songs with extremely limited knowledge of theory. I think I could have written a lot more (and better) if I had at least known what rules I was breaking. Don't assume everybody who uses BIAB is versed in even the basics.

If I have overlooked resources of this sort which may already be in BIAB, please direct me to them.
