TermKit was one of the inspirations for Extraterm ( https://extraterm.org/ ). It separates command output, allows for reuse of previous output, as well mixing content types.

The terminal VSCode has been picking up on these kinds of features lately. Now they can even "sticky" the previous command line at the top of the window when scrolling through long output.

It has taken a long time, but these ideas are slowing spreading around.
