Mission (Out of )Control

Back in the day, it was easier to tell what app it was! (Image from MacWorld.com)
I use Mission Control in OSX all the time. But I also have a dozen apps open most days. It’s hard to tell, the apps apart sometimes. Is that Chrome or FireFox? I always wanted Apple to bring back a little app icon to the tiny representation of the app. I did learn something recently that might be a useful if you suffer the same pain.
You can use quick view while in Mission Control. When the tiny window is highlighted, tap the space bar to make it bigger.
