Ideas for chord selector

Instead of having a limited selection of chord types to choose from, it would be a good idea to be able to choose the main chord type (major, minor, dominant, sus), and then by selecting any of those chord types, a drop down menu (or a new window) would display all the different chords from that selected chord type.
For example, if I select "minor", it would display all the following minor chords:
m, m7, m9, m6, mMaj7, m7b5, m7b6, m(add9), m(add11), m11, m13, m7(add11), m7(add13), diminished, diminished 7, etc...
Same for the major and dominant chord types.

I hope a setting to save my chord choice. The voicing is lost when you close the music score. At each time you do rebuilt the set of chord.
But i have a good think of ireal, Thank.
