Notes on your games. Jot down what you worked out on any move and come back to it later.
Sticky mistakes. Puzzles you got wrong stay in their own list so you can drill them again.
Play from here. Take any position from a review and play it out against the engine.
Exact endgames. With 7 pieces or fewer you now get a flawless answer.
More puzzles made from your own games.
Fixed the day streak and the review ticks that kept vanishing from the game list.
