I’m on Tuxedo now, really nice so far. Thanks.
For now, NC Deck does what I asked. Even if it’s bound to Nextcloud, that’s at least a server I trust. I also used Markor as my editor ever since switching to Android, it seems to have a todo-focused Markdown extension with linking other files. Looks powerful, maybe I can build something with it.
Good to hear. Having a raspberry and kodi focused base with an open Linux backend sounds good. Will try that later.
