As a user, I can't easily see at a glance which window(s) below to which app(s) in the Ctrl+Tab preview list.
Suggestion: the same as for dock peeking, consider displaying each app's icon and name in the Ctrl+Tab preview window list. Specifically, show the app icon/name only for app's first window in the list. Or, implent other UI changes that would help users identify at a glance which window(s) belong to which app(s) in the Ctrl+Tab list.
