Hey! I use trilium notes quit a bit, I've just gotten into the scripting side of it, it does suffer from a lack of documentation in my opinion. But it's quite good.
I would be interested in joining/creating a community
It's a note app like obsidian.md. You can host it yourself also. It's very capable and I think it's much easier to use compared to Obsidian, just that it doesn't has as much articles.
I don't use Trillium, tried once Obsidian but it's not free. Have you tried Joplin, it's free works extremely well with Dropbox or NextCloud for syncing between téléphone and the PC. For note taking its extremely good
Obsidian is free if you use your own cloud storage to sync your note.
I tried Joplin, but so brief that I don't remember why I dropped it. Back then I was hunting for an alternative to Notion. May give it a try again. How do you like it?
I've used Joplin for years now before was Evernote. I like it because it's open source and the syncing option is built in, exemple either to Dropbox or NextCloud (I use both these options, DB only because I have a free option of 12gB otherwise I would use just NC) The syncing is painless as as I said built-in. It's not a pretty app, fairly plain, but it works perfectly, on my android and Linix PCs, Arch and Debian.
I did try Obsidian once. It's pretty, but not being open source put me of. Try it again, takes minutes to set up, as again open source and works well
