Does anyone use the packet list and protocol tree selection mode
preferences? A long time ago in a GTK+ version far far away you could
click-drag in GTK_SELECTION_BROWSE mode and have the selection follow
the mouse. Now GTK_SELECTION_BROWSE and GTK_SELECTION_SINGLE behave
nearly the same, with slight differences when you hold down the shift or
control keys:

I don't think those differences are significant enough to warrant using
up space in the preferences dialog. In a similar vein, does anyone use
the right/left scrollbar placement preference? Unless anyone objects I'm
going to deprecate them.
