non-major 7ths, 9ths, etc.
I generally really like this app. I dont use the sound, so do not have the complaints that some of the others do. However, I am amazed how confusing it is to find 7ths, and 9ths chord forms. While it is fine for things like G (triad), and Gmaj7s (for example), finding alternate forms for seventh chords like G7 is impossible. This is a major omission.
