because if you have many windows open, and you chosen to minize them, when looking at window catalog it would be helpful to preserve that information. Minimizing them means in some indirect way that they are less valuable to you at the moment then the windows you've kept open. So when you're looking at them through window catalog, ideally the "important" ones would appear large, and the "unimportant" (temporarily) ones will appear smaller - just like its done on a mac

Should I add this as a feature request?

No, there's no way to tell. Why would you need to know?

Hello,

I am wondering if there is a way to tell which windows are minimized in a window catalog/ fullscreen preview?

Thanks
