Could it be possible in the future to have the option in the chord symbol system to omit some notes out of the chords?
For example, in jazz fusion, rock, pop genre, there are many chords such as:
C(omit3) = C,D,G,or
C7(omit3) = C,G,Bb etc..
and for minor chords:
C-9(omit7) = C,Eb,G,D (could also be spelled C-(add9)

I know that in the app, there are already some options such as C2 or C5, but it's pretty limited, because it only works for basic triads.
The idea would be to be able to add on any chords something like "omit" or "no" followed by any number the user can insert to remove a specific note from the chord.
I would suggest a similar idea for adding notes (using the word "add" and let the user type any number that correspond to the note he wish to add)
Example: Let's say I want to edit the chord C(add4). It's a C triad with a fourth (C,E,F,G) commonly used in rock or pop genre. If I add the number "4", after the word "add" it would automatically add a 4th in the chord. Same principle to remove a note from a chord using the words "omit" or "no".

Other questions about chords symbols:
- What's the difference between C with the triangle (C∆) and C with the triangle AND the number "7" (C∆7)?
The triangle symbol usually means there's a major 7th in the chord, so why the need of having a symbol with both the triangle and the number "7", since the triangle already means a major 7th is added? It's kind of confusing.
- Same thing about the half diminished symbol (ø). What's the difference between Cø and Cø7?
Cø usually means C half diminished (C,Eb,Gb,Bb). It already includes a "7th" otherwise it just becomes a diminished chord (C,E,Gb).

Thanks for your time to read this and looking forward for some new upgrade.
Great app!

All the best
