As much as I normally hate this sort of thing, it might be a nice touch to
make Evolution prompts to make sure you meant to close the main window
(with a checkbox to say "Never ask me again, you stupid computer" for most
people, of course)

Normally these are obnoxious, but I (and other people; I've seen mail about
it on various lists) have sawfish focus problems periodically, where it
doesn't catch that you've moved to another window. This seems to more often
than not bite me when I move my cursor from evolution to another window,
and hit my keyboard shortcut to close it, and wind up killing evolution by
mistake.

I would ocassionaly do the same thing with Galeon, but fortunately that now
prompts if you're killing a window with multiple tabs, which made me think
to file this.

So this isn't a really critical issue, and most people probably would
disable the feature, but I figured I'd ask, just in case someone thought it
was worth doing.
