> I noticed some kind of error coming up in trying to export to pdf

Ah sorry, not entirely unexpected actually, as for the moment the saving/loading functionality on Firefox and Safari is a bit broken.

The functionality relies on a newish Web API only fully supported by Chrome / Edge, and I haven't implemented proper fallbacks yet (the plan is to make an Electron app, which fully allows working with local files, but an adequate fallback should be provided for all browsers regardless).

Definitely an option. Supporting different export formats is on the horizon. Feel free to open an issue / discussion about independent png/svg as well!
