Same, except s/notepad/vim. One big file. Easy to keep in version control (I keep it in my dot files repo), easy to search/grep, Currently has 10 years worth of stuff (well over 10,000 lines) but is still instantaneous to open and search. I've recently started trying out Logseq and there's a chance I may actually switch, but the single-text-file approach has served me very well for a long time.
