One search across your home tabs

Your home's tabs are now scopes of one search: type a term once and switch between Shared with me, Pinned, Apps, Spaces and the new All tab — the search follows you, and All searches everything you can read at any depth. The search bar and the ordering controls sit on one row on desktop; on phones the bar steps aside (the top search covers it).

Tidier tabs, too: apps no longer flood Shared with me (they live on Apps, which now also lists everything you've installed from the Store), and other people's user spaces no longer appear as shared content.
