Hi HN,

I built leaf, a Markdown previewer that runs entirely in the terminal.

It supports keyboard/mouse navigation, syntax highlighting, tables, checkboxes, clickable links, search, table of contents, local Markdown links, inline images, Mermaid diagrams, and LaTeX-to-Unicode rendering.

It works on Linux, macOS, Windows, and Termux.

GitHub: https://github.com/RivoLink/leaf

I’d appreciate feedback on the UX, missing features, and performance on large Markdown files.
