I don't know about you, but I think that the disk, memory and history info
is actually *useful* and really should be provided as normal user menu
options, rather than obscure about: URLs.
You missed two which won't show up using this method:
about:jwz Gives information about Jamie Zawinski; click on any of
his links and the animated Netscape icon will become an
animated compass icon.
about:mozilla Gives an amusing biblical-style message and, even more
amusing, any URL you access from now on will show an
animated, fire-breathing Mozilla in place of the normal
animated Netscape icon.
