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
Out of curiosity, what do you use it for? What things do you save there?
All my notes for tabletop RPG stuff, mainly! I run a few Pathfinder campaigns.
