my deepest darkest secret is that i secretly really like macOS Stickies.app to jot things down with just enough WYSIWYG markup to capture an idea (before I immediately shuffle the idea somewhere else, e.g. emacs).

the application itself is relatively hideous, and I kinda see that as a feature (because the app is not particularly fit-for-use for just about anything else besides a quick "tmp" buffer with RTF).

Just wondering if MacOS people have looked at Eastgate Systems' Tinderbox application? I was a happy user back just after the Millennium.

(For me on Linux it is a directory full of text files with markdown and sometimes a groff pic diagram or even a metapost diagram (just starting with that one))
