I think the biggest pain point for me is that nothing I've found supports cards that can be "flipped" so that they are face up or face down. I'm not an advanced coder but maybe I'll try to whip something up.
tldraw does look amazing though, thanks.
Ooh I see PixiJs can make content available to the screenreader for a11y. That’s always a big question mark for me when people start cramming a content tree into a canvas.
Yes a11y is very important! I do think this creates an HTML element per sprite/graphic, but the slowdown should not be terrible.
Last I checked Miro also uses Pixi so that's another quality infinite canvas app.
