I've been using Obsidian for a long time. I enjoy it and all of its extensions. However setting up the app and syncthing on all of my systems gets irritating.
Any way, after a little looking around, I found Trillium notes. It doesn't quite have all the extensions, but is easier to setup. Give it a look, see what you think
It sounds like you may like NixOS if you haven't tried it
See, now i'm going to have to find another PC to install that on. Lucky for me I have 2 less things to install, now my notes are hosted on my server
