also, on the markdown front, I saw this cool library https://github.com/Canop/termimad gaining popularity

Termimad author here: I’m always a bit afraid, when I see the popularity of this crate, that it might be undue and that people may lose time trying to use it when it’s probably not the tool they need.

Termimad isn’t a full-fledged TUI framework. It can be used to build TUIs (I made broot, bacon, safecloset, etc. with it), but if you want to quickly build a TUI and compose UI components and widgets, you’ll probably find it much easier to choose a real TUI framework (e.g. ratatui).

Termimad isn’t a generic Markdown viewer either. Markdown is mainly used as a language for the developer to describe parts of the interface—especially rich text—inside a TUI. People interested in rendering arbitrary Markdown files will find that it lacks features such as image rendering.
