You can export excalidraw files as images or svgs. My main issue has been subpar support for Samsung pens, which is in part due to Samsung requiring an SDK to detect button presses or gestures... which means hitting the toolbar button to erase stuff

It tends freeze and mess up your writing when it autosaves. Not much of an issue if you set it to every 5 minutes, but annoying at the 15 second default.

Lastly, large drawings have performance issues. A few "pages" of notes and you can start to see the renderer struggle to track your pen correctly.

Tbh I'm probably just going to use another app and export images into my obsidian repo.
