Well... it does and it doesn't.

   You slightly misunderstood the bit about the base struct. base isn't
actually a window at all, but just a struct to hold the "real" windows...
which means that I actually don't have the problem of mistakenly closing the
whole app like that. In my particular case, I also don't have to worry about
dynamically adding windows, so that's not an issue either.

   But anyway, aside from that one difference (base struct as opposed to
linked list), the solutions sound like they're pretty much the same. Which
doesn't help my primary problem, in that I'm carrying this huge global
dataset around, which I don't like. But it does seem as if this is a
more-or-less "standard" way of doing things.

   Well... thanks anyway.

   If anyone else has another way of doing it, I'd love to hear about it!
