Did not expect the ethoslab shout out, I fell off a while back but I followed his videos pretty religiously for many years back in the 2010s; even when I was going through times where I burned myself out on playing MC.
Dude is super wholesome and I loved how his videos kinda just felt like hanging out with a friend. Ive checked on him since and I respect that he has not changed at all, love him dearly. But it just doesnt hit the same for me as it did back then. I hope he keeps doing what he loves as long as that's still the case!
Honestly, Google Keep notes. Trilium server runs as a UWA on Android but it's pretty ass. And things like Obsidian are way too much for something me and my (non-technical) SO use to share notes
