So Windows 11 introduced the option to group windows by using the snapping layout feature.
It also allows you to show the group when alt-tab-ing or when hoving over the windows on the taskbar for example (Settings -> Multitasking -> show snapped windows when I hover over taskbar apps, in Task View, and when I press Alt + Tab).
This is a great feature but there is a single flow with it. When a user decides to treat with these windows as a window group and not as individual windows, the OS should do too. What I'm trying to say it, when you enable this feature and alt+tab for example, I should see the group listed but not the individual windows as well. That pollutes the alt+tab screen a lot and ultimately makes the screen unusable. Same for the taskbar icons.
