Hey single-screen folks — we heard you :D
• New: Translucent drag-out preview — when you drag your finished image to Finder or another app, the VAS window goes semi-transparent so you can see the drop zone clearly. No more guessing in the dark!
• Improved: Consistent annotation sizing across canvas types — Callout / Number / Symbol / Text annotations stay visually stable when switching between standard / Hi-DPI / long screenshot / whiteboard canvases
• Fixed: The in-app User Guide link now opens the correct language manual page based on your interface language
• Improved: Smoother toolbar interactions
Yours, VAS
