Improved selection UX to match professional DAWs: - Drag directly on waveform to create selections (no modifier keys needed) - Click without dragging seeks playhead and clears selection - 3-pixel drag threshold prevents accidental selections - Fixed variable name conflict with existing file drag-and-drop feature Users can now naturally drag across waveforms to select regions for editing, providing a more intuitive workflow. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
