I like Plan 9 terminal somewhat, even though it's infuriatingly simplistic and non-ergonomic: - the idea of the terminal as a document which can be navigated is pretty interesting (tmux fixes this to some degree). - the possibility to display other types of content directly inside the terminal window (e.g. man-pages rendered as pdf inside the terminal window), although it was not a terminal feature, but the feature of rio.
