Comment 3 for bug 1193419

Well, all of them have dynamic categories (when you search), but for surfacing it's the only one currently. But due to lack of data or for other reasons, every single category might disappear for any reason. If it's empty - it goes away, that's about it.

But! That's why, when you long-swipe from left from an app, it's considered going to "spread" - at this point the Apps lens is indeed scrolled up to show the running apps. When you're already in the Dash, it doesn't matter where you click on the app - whether it's installed or running (or Launcher, of course) - it will take you to the app.

The Launcher is also supposed to have (some?) recent apps (like the ones running on the desktop) at some point, maybe that'd solve some of your issues.
