I think ReMarkable is wasting a TON of potential at their price/form factor/ux. A device can be powerful without sacrificing simplicity and singularity of purpose.
I've had my rM2 since 2020 and enjoyed the hacking community a lot. I've since lost track - at some point I updated the firmware because I wanted the automatic shapes feature from upstream and couldn't use the framebuffer anymore.
You've summed up a lot of findings that I've made again and again trying to pick up where I left but it's become very confusing.
Looking forward to your next update! No pressure, though :)
I've just remembered: Check out KOreader if you haven't. I think it doesn't rely on QT and it runs on rM2 tablets with recent firmware if you launch it via ssh after stopping xochitl.
The API hacking scene is very much dead. Most API implementations have been unmaintained for years now and no longer work. It's a real shame.
RSS or Pocket client?
But no, nothing, just the subscription stuff. So it's a no from me.
