I have added a new summary panel to enhance the puzzle-solving experience.
From now on, at the end of every puzzle session (except for the Daily Puzzle), a summary will appear listing every puzzle you didn't manage to solve during that run. The panel provides a dedicated button for each failed puzzle, which opens the specific puzzle page on Lichess for analysis.
This is the first step in improving the puzzle review process. In the future, I plan to develop this feature further.
I hope this feature helps you sharpen your tactics and learn from every session!
