Collapsible headers

As I see it right now, having the sections be collapsible here is a good idea. However, why even have it at all if the default is to have the sections visible? Since preferences aren't saved when you leave the page/reload, closing a section that's open by default doesn't really do anything unless you're too lazy to scroll down.

On the other hand, if the various sections were instead HIDDEN by default, this would eliminate (mostly) the need to scroll down for pretty much everyone, allowing them to easily reach whichever section they wish just by clicking it open. I dunno, that just seems like a better way to use the system...otherwise, I don't see a point to it at all. What do you guys think?
