Thanks for making this, just gave it a try. You might be able to work with the chess.com people in a way that might generate some $$. Or, better, work with the lichess folks (not for $$). I'd like to be working on something like this. Meanwhile, I think I'll run it some. Holes in my tactics especially in blitz showing up too often at the local chess Meetup.
