One thing that's rarely mentioned about this device, but is the reason I sprung for it, is that the developers left an SSH interface into the device over USB, so you can program custom apps! People have made some neat stuff, and there's a Rust library for making apps: https://github.com/reHackable/awesome-reMarkable
This is what I was looking for and their website fails to mention it on the landing page, at least. Would you know of any Emacs/org-mode extensions for this device? Thank you for sharing!
I just got a polar/readwise/orgmode/Anki setup together and I'd love to use this.
