9 months ago I think this is basically #12, right?
I think we'll need #12 anyway if we are going to support the full suite of black chord inversions, so I'm thinking there will be the regular mode, and then a "free chord choice" mode where you tell it how many chords to show and which ones to choose from, and it shows you a random assortment of those. For example, if you told it to show you just the black chords and 2 of the inversions for the black chords, and said to show 5, it would pick 1 chord as the "correct" chord, then 4 decoy chords from the array.
That said, I have found that the automatic re-weighting does a pretty good job of de-emphasizing chords you already know. My son is on purple now, but the only chord that gives him trouble is orange (he usually confuses it with green). When I do it with him, it's mostly green, orange and purple, and probably 1-2 of each of the other chords per 30-chord session. I would expect the same thing to work fine with the black chords — whichever one your child is struggling with should be weighted most heavily in the selection.

It would be nice to be able to focus on just the black chords to ensure sufficient practice after mastering the white chords.
