There are quite a few. In order of preference, I used/tried:

• XMPP (Android-Conversations; Windows-Gajim)
• Element/Matrix
• Session
• Discord
• Slack
• Twinme
• Teams
• Skype
• Facebook Messenger
• Instagram DMs

Falling Lightblocks, available on his own website or GitHub.

In hindsight, that’s what I’d go for. You could have audiobookshelf, tachiyomi or any of your favorite android reading apps. But the Kindle does what it does well, and for relatively cheap. Maybe in 5 years I’ll reconsider, if my kindle ever dies!

I personally enjoy the sliding feature, which also utilizes the right side but without taking any space. Sync and others have it.

Already am! Just used to GitHub and thought I could see a list of what’s being worked on. I imagine beta update posts will bring some light to this.

Thanks!

Thanks for the confirmation! Is there a way to follow development?
