Very cool project!
That would be great if I could drag the mouse to draw instead of just clicking.
An "export area" would be a nice-to-have feature in the future as well.
My initial implementation actually did exactly what you suggested where you could drag the mouse to draw. I ultimately moved away from that approach, mostly because it made it way too easy to "spam" the canvas by quickly drawing random pixels all over the screen. Requiring users to draw pixel-by-pixel forces drawings to be a bit more intentional. The UX also gets more complex when a drag can either mean "draw" or "pan", so having a drag always pan the canvas simplifies things.
As for an "export area" feature, I also considered that, but figured people would rather just use their device's screenshot functionality. It's still something on the backlog that I'll prioritize if I hear similar feedback though.
