Lime
I've been working on a beautiful markdown reader for the terminal. It uses the kitty graphics protocol to render big headings. It works by loading your file into scrollback and using apple events to jump around scrollback rather than re-rendering the section you want so it feels like reading a pdf in your terminal. Ghostty + macos atm, but might expand to other terminals supporting kitty. https://github.com/spencerldixon/lime
