What do you think of the second option that allows the user to force others to see that nav bar? Most of the people who do it mostly leave it because it's the LJ default and/or they don't find it intrusive. I would really like that second option to be removed, because it really irritates me. That, or a third option that states: "Never show the navigation strip when you view any journal or community." I know it's a small thing, but that navbar distracts me, and it's starting to piss me off.
