- Added SGF import: load game records by selecting a file or pasting SGF text - Improved replay controls visibility in fullscreen mode

- Added a toast notification when the AI passes. - Fixed a bug that caused games to become unplayable in certain situations.

- Improved board interaction Placing a stone on larger boards (19x19 etc.) now feels more natural and uninterrupted. Tap to zoom in, tap to place your stone, and the board automatically zooms back out — keeping your thinking flow going without any extra gestures. Previously, you had to double-tap to zoom back out after placing, which interrupted the flow and made the board feel sluggish (internally, the app had to wait for a possible second tap before responding). That double-tap detection has been removed entirely, making every tap faster and more responsive.

• Fixed an issue where the "Resume interrupted game?" dialog would appear even before a game had started.

• Optimized the UI rendering engine for improved overall app performance. • Fixed a rare crash that could occur in specific environments or during certain rendering timings. • Resolved an issue where the result screen could unexpectedly close due to consecutive taps at the end of a match.
