- Creating a notebook now auto-navigates to its first page editor (createNotebook returns ID via callback, triggers onNotebookClick) - Double-buffered rendering: all layers composited to an off-screen bitmap before presenting to the display in a single drawBitmap call. Eliminates visible intermediate states (white flash between layers) that caused flicker on e-ink displays. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
