I just released StitchBuddy 3.3.2 (macOS), addressing some minor bugs and improvements:

• Rulers are indicating dragged mouse positions
• Context menu item to close all open subpaths
• Open subpaths are handled when filling shapes
• SVG paths with identical start / end points are closed
• Feedback if no SVG path was imported
• Quick Look plugin is reflecting thread numbers

The new version will be distributed in waves and automatically updates your Mac (depending on its system settings). And you can manually install it from Apple's Mac App Store at any time.
