Drilling down this list helped me to find https://notable.app https://notable.app by @fabiospampinato It looks like a beautifully simple Markdown Notes Desktop App (Win/Mac/Linux). Have just been playing with it to import plain .txt files lying around on my Desktop. Has a simple out-of-the-way UI for creating markdown pages, organize active ones in tags, favorites or pin to top. Saves as plain .md files in 1 folder. Zen, floating & translucent modes. Looks like a TODO.txt notepad.exe replacement that might stick.
