I installed this open-source app on my Kindle and it instantly made Amazon’s software feel outdated

My 2015 Kindle Paperwhite has had a strange retirement. I jailbroke it and mostly use it for its Linux capabilities, running it as a Home Assistant dashboard instead of showing me books. KOReader, the open-source reading app that tops any list of the hidden features jailbreaking your Kindle unlocks, came along for the ride when I set that up. I never read on it, because it opens to one of the least welcoming interfaces I've seen on an E Ink device.
