I switched from nVALT to FSNotes, and then to Obsidian. FSNotes was too buggy for me. In particular, I'd go to search for something and somehow after a few characters I was randomly typing in to some saved note. Obsidian has been excellent. I suggest dragging the "magnifying glass" icon to it's own "tab" so it's always visible (something I'm used to with nvALT / FSNotes).
