I want this but for ePaper tablets like Remarkable.

This is for epaper tablets, just tiny ones.

Remarkable looks like it has a pretty active hacking community: https://github.com/rehackable/awesome-remarkable#launchers

I had a similar thought but thinking it through, would probably lose the near-zero-lag stylus stuff. That's kinda rM's whole thing, not ebook reading.
