Uninstally 1.4.2

Added

• Collections — create your own tabs in the main sidebar to group and
  categorize apps.

  Collections are great for trying out apps you plan to remove later: when you
  download something to test, drop it into a "Trying Out" (or "To Delete")
  Collection so it doesn't get lost among your everyday apps. When you're done
  evaluating, open that Collection and uninstall the app — along with all its
  leftover files — in a couple of clicks. Other handy uses: grouping a project's
  tools, games, or apps you're deciding whether to keep.

  Add apps by dragging them onto a Collection or right-clicking an app →
  Add to Collection. Rename, pick an icon, reorder and delete Collections from
  the Customize Sidebar sheet. Collections are organizational only and never
  change what's installed; they persist across launches.

Changed

• Sidebar customization now lives in the main application window (not
  Settings). Settings is a single, fixed page again.
