I don't know that make is a good example here. This is a tool you use constantly, so I imagine you'd know to pipe std err if you wanted its output. We seem to be talking about turning the terminal into a full blown editor (when we already have editors...) to satisfy a rather limited use case of 'oops, guess I have to run that again."

But hey; your time to spend :)

That seems like an incredibly common use case to me. It's common for a command to have a lot more output than I originally expected, and when it happens, I usually want to examine that output in detail. It would be great to retroactively be able to open captured output in a text editor, dump it to a file, pipe it to another tool, or collapse it.

I don't really want to edit the output in the terminal, but it would be great to be able to say "oops, do X with stdout from that last command, and do Y with stderr".

FWIW, I also find myself wanting this.
