Well, 80x24 is basically the minimum size I'd reasonable support. It's
the resolution specified by the VT10x, so I would say it's safe to
assume that every video output supports at _least_ that. It's also
what's used for serial output. See also e.g. commit 3facbe51c [0] or the
VT100 technical manual [1] some more in-depth information.

And since the target is pretty defined for this (always fullscreen on
some video output, not some resizable graphical terminal window or
such), so I think supporting anything less would be a lot of work for
pretty much no return.

The disk view is scrollable and should scroll as needed. Tested this
with ~12 disks.

Yeah, that's what I thought, but I wasn't sure. It would also match the
GTK installer in that regard. The side-by-side is quite nice on wide
screens though, but no hard feelings :^)
