UI Suggestions for blind tactics

Hello, and thank you for such a clever way of improving visualization skills!

I have a couple of ideas for improving the usability of the blind tactics page. They are:

have a "Give up" button. Not sure what should happen when pressed, but at least reveal the solution (in algebraic notation), display the final position, and make a "next puzzle" button appear
Allow user to flip the board, so we can do puzzles as black with white on the bottom
for users which simply "can't see it", maybe have a button to advance the state of the board one ply at a time, so if I'm say, playing with 8 ply hidden, and I can't see it, I can "incrementally reduce" the puzzle to a 7 ply, 6 ply etc until I think I can finally see the solution.

In any case, lovely work and look forward to see how this project progresses! Cheers!
