Initial draft with UI changes

@gwprice and @mhoeber , this still needs changes to policy key settings/new images for the Studio changes that will be in tomorrow's release. Also, most of the paragraphs are not wrapped onto new lines, but I didn't want to distract from where I actually made changes. I'll do that later.
@lamagnifica - I think it makes sense to move away from the use of thread in general, but if you feel it is important to keep a distinct label separate from post for this we can discuss, or adjust in a follow-on PR to not prevent this from merging before the release.
