Metacity won't allow the toppermost edge of windows to be moved "above" the
screen, so to speak. I'm currently running a course for newcomers, some of
whom have less-than-perfect vision and consequently we've standardised on
800x600 on our machines. With non-resizable dialog boxes that extend
beneath the screen, this makes it impossible to locate the items at the bottom.

I understand the principle of "least surprise", but nigh-on every window
management system in existence permits this and we've just moved to KDE as
a result*. You allow a toggle for maximize/shade titlebar double-clicking,
which would be even more surprising for a newcomer!

Having this as an option would be superb, and we could consider using GNOME
again. I understand and appreciate your desire to keep things simple, but
when they make it unusable in common scenarios, that's bad. I prefer GNOME
to KDE, but at least KDE lets the user set up their desktop for their own
needs, and not what the developer dictates.

Thanks for reading.

*A couple of other things have prompted this: no wireframe mode (waste of
CPU), no way to disable minimize animation (ugly, but still cosmetic), and
the shockingly awful taskbar (on a small-size panel), which inserts newly
opened windows at random positions. Open window with three already in the
taskbar, and it appears at the beginning! The UI studies have done some
marvelous work, but that's a real clanger. Anyway, most of these have
already seen bug reports filed, but little work... Again, it'd be nice if
the users could decide how their desktop works.
