I've added one.

I've also changed Ethereal so that there's a "Capture" item in the
"Edit->Preferences" dialog; that allows you to edit all the capture
preferences, including the interface.

In addition, I've changed things so that the "Capture->Start" dialog
does *NOT* affect any of the preferences; the only way to change your
capture preferences is to edit them explicitly.  The preferences are
used to provide the settings for the first "Capture->Start" dialog;
on subsequent "Capture->Start" dialogs, the settings from the previous
dialog are used.

The interface preference, but not any of the other preferences, affect
Tethereal; the "-p" flag can only turn promiscuous mode off
(tcpdump-style), it can't turn it on, so Tethereal ignores the
promiscuous mode preference (if it didn't, then if the preference were
"don't run in promiscuous mode", there'd be no way to override it), and
the "Update list of packets in real time" and "Automatic scrolling in
live capture" preferences don't apply to Tethereal.
