If you use Apple Notes on a Mac, you might enjoy ProNotes.
It’s an little app that can watch what you type in Apple Notes and on certain triggers, such as #, ## or [] it converts your text to Apple Note’s formatting:
I miss a couple more options that could be auto-expanded, such as > for block quotes, ``` for code blocks and single backticks for inline code. Maybe future updates will bring those.
Beyond keystroke expansion, ProNotes also provides a medium-style floating formatting toolbar, that appears any time you select text:
I like that every feature can be turned off. I really don't need any more menu bar items and I can imagine the floating toolbar become annoying soon. Here you can see the apps current settings:
It's free (as-in-beer) and can be downloaded here:
