• Collection scans show their progress: what the scan is doing (finding games, reading
  each item, finding names and covers, saving), how far it is, the item it is reading and how
  long it has taken; afterwards, when the last scan finished and how long it took.
• One scan at a time, shared: pressing Scan while one is already running (the automatic
  refresh, or another window) follows that scan instead of saying the collection could not be
  read.
• "Import from PS Game Library" is gone.
