>Before I was able to see my contact list under the list of folders. Is that possible anymore?

I tried to find a way to do it, too, but I don't think you can. Use the Contacts folder or toolbar or hotkeys.

>Also, I was able to not show the header which appears right after the toolbar indicating on which folder we are. That header appears in grey shading. Is it possible to not show it as well?

O2K shows the active folder in the title bar, just as good, I figure...
