In mission control, I couldn't see Application names below thumbnails if the cursor is somewhere else. See this image. If I move the cursor onto any thumbnail, then I'm seeing the application name. Is there any setting that enables even if the cursor isn't hovering on the app thumbnail. Like images in this answer. Desktop 1, Mail, Desktop 2, Desktop 3 are appearing all at once and cursor isn't on those thumbnails.
It turns out once we have over 12 or so spaces it starts to have this zoom-on-hover effect with the space descriptions hidden. We cannot change this behavior. Source.
You might want to turn on "group windows by application" in System Preferences -> Mission Control. This has a payoff which you have to decide :). You won't be able to see full window when they'll be stacked. This can be overcome by hovering the cursor on a window and press the space bar to zoom in only on that window. You can also swipe up with two fingers on a window group.
Personally, I keep grouping off and just quickly switch once or twice between mission control(swipe up) and app expose(swipe down) and see what windows are present. I just developed a habit, can be odd for people.
