I've started doing notes in the terminal as well. I used Obsidian and Logseq for a while, mainly because I wanted something with a GUI so that I could recommend it to people who aren't comfortable with the terminal. But eventually I figured that a terminal solution was the right one for me, since I have a terminal open all the time anyway.
I switched from vim to kakoune a while ago ( https://kakoune.org/ ), so I use nb ( https://xwmx.github.io/nb ) instead of vimwiki.
nb is a terminal application that will open whatever your default text editor is.
Looking forward to reading it! awk has been a huge blind spot for me for a long time now.
