+1 to this, it would be super useful to have some light reformatting of the markdown generated by the agent (possibly when it's done generating its response? So the overhead is light and we don't try to reformat partial markdown)

Glow has been a stable alternative for a long time to render markdown in the terminal and is pretty fast for large documents.
