Featere requests and bug's

[Deflider]

Hi! I mostly use InfiniPaint on my mobile phone. I absolutely love the app and think it's a fantastic project, but I’d like to suggest a few features and report some bugs to help make the mobile experience even smoother.

Feature Requests

• Two-finger tap to undo: Adding a two-finger tap gesture for "Undo" would be incredibly helpful. It’s a standard feature in many mobile drawing apps and drastically speeds up the workflow.
• Manual "Force Save" button: It would be great to have a way to manually save the project to prevent data loss. The app has crashed a few times while I was drawing, and I had to start over from scratch. I completely understand that the app is still in active development (especially on mobile), but a quick-save button would be an amazing safety net.

Bug Reports

• Canvas displacement after minimizing: Sometimes, after minimizing or switching away from the app and coming back, the canvas glitches out or "flies away" into the distance upon the very first touch.
• Phantom touches and stray marks: I experience a lot of accidental inputs while drawing, panning, or zooming. The app frequently leaves behind stray dots or lines that I constantly have to erase.

Thank you so much for your hard work on this app! I look forward to future updates.
