That sounds odd. The idea regarding windows is about keeping multiple 
stacks at the same time, not about discarding information.

Maybe you never do? Or if you really do, that would require some 
additional manual management (through new commands, I suppose).

In my book that's starting a new line of thought, where it's okay to 
create a new stack. The old one is still around.

I don't know if it's practical or not, but it requires some additional 
design for sure. Maybe someday.
