title: Is it possible to mix a 'preference' and a preference header?
body: <p>I am developing a list of preferences for my app. Right now, there is only one, but I am sure there will be more as it gets fleshed out. My first preference is a 'theme' selector, where you choose the background color theme for some predefined elements. </p>
  
  <p>I want a dual-pane interface for my upcoming prefs, but I don't need this preference in a 'subcategeory' that preference headers use. Is there a way to add a 'preference' (via XML) to the headers list so it will appear in the root preferences? I've looked... haven't seen any examples on if this is possible. Right now all I have is a button for 'Themes', which goes to a new preferences page (another fragment it lives under) which is making 2 clicks instead of one for a preference that doesn't go under a category.</p>
