how the Mac computer uses the Windows under Mission Control as a group
The good news, though, is that when we use Mission control, we can group similar applications. More importantly, when grouping is enabled, all associated applications are placed in a single window, and the corresponding application icon appears below the window.
Obviously, with the icon, we can make it easier to identify a particular application window. Next, let's look at how to do it.
1. Open System Preferences and enter Mission control.
2. In the pop-up window, check "make Windows grouped by application."
3. Next, we can go to the Mission control view to see if the application is already in a group.
At this point, we will find that the application is not only a group, but also the icon of the application under the window of the group, which is helpful for finding the window that you want to open in Mission control.
