9 Commits • 3 Features
Apr 1, 2026April 2026: Delivered cross-platform keyboard UX improvements, stronger LSP reliability, UI style configuration enhancements, and build stabilization. These efforts reduce platform-specific input surprises, ensure reliable incremental builds, and improve developer feedback in live previews and editor workflows. Notable work includes macOS keyboard translation suppression to preserve Slint shortcuts, improved Windows Ctrl+Alt/AltGr disambiguation, clearer errors for localized shiftable keys, LSP watch-for-file-created events with tests for editor-name changes and unresolved path handling, SLINT_STYLE support for style suffixes with improved live-preview missing-file messaging, and a winit Cargo.toml dependency conflict fix for a cleaner, more deterministic build.
