I'd like to see simpler chord figures ...able to be written bigger, yet taking up less space, eliminating unnecessary clutter.

f- ...lower case with minus sign instead of Fmin
F^ ...instead of Maj7
fo ...instead of Fdim
F+ ...instead of Faug

Also I'd like to use lower case for indicating bass notes with inversions ..making it distinctly different to avoid confusion

F/c ...instead of F/C
