- Lines can now be clicked to select them (with wider hit area for easier clicking) - Selected lines highlight in amber/orange color with animated flowing gradient - Animation shows direction from source to destination (hue moving left to right) - Pressing Delete key removes the selected connection - Clicking canvas background clears selection - Added arrowhead marker for selected state in amber color - Physics state cleaned up when connection is deleted
