There is a window manager program called, appropriately enough, wm.
It allows you to interactively create a number of windows,  each of which
can contain a separate process.  As you move between windows/processes, the
output on these windows is restored, so it appears just the way it was when
you last left it.

The program was sent down the net quite some time ago. Since it uses termcap,
it should work on any terminal having a termcap entry.  I'm attaching a portion
of the man for reference, below:
