Toggleable finger placements for chords

It would be helpful to allow showing common finger placements to learn new chords, or to view how to play a chord you don't remember.

I've been thinking about how to display that since all chords are generated out of music theory. I could code in all combinations of all triads, augmented, diminished, 7th etc chords for all 12 keys but that seems a bit silly to me. Especially when I want to bring in melodic and harmonic minor chords. Or bring in inversions. The combination completely explode.

Would it not be more beneficial to understand how a chord is constructed? That way you can play everything, anywhere. Even though I may take more effort initially, the return in investment is much greater.
