It's cool, and I feel dickish being like "Someone made a cool thing? Those suckers, we already have cool things", but you could get a lot of the same functionality by building on top of other open-source minimalist diagramming tools, some of which I can see have been mentioned in other comments, and just adding on assets for D&D specific stuff. Like I'm not sure what I could do with this that I can't do with excalidraw.
But in terms of more useful feedback
- The way the canvas expands when a line is close to the edge is very clever. It might be useful if that could be done in real time somehow, so that if you're drawing a long line the canvas can keep up with you
- Some more erase and selection options would be cool, if I have to delete a big structure that I made out of a bunch of tiny line segments I think the only way I can do that is individually clicking them.
- Zoom seems kinda janky for me, that might just be my browser (Desktop Safari). Also if there's a way to pan I couldn't get it to work
