In GNOME 3, I can open the Activities overview by clicking the 'Activities' button in the top-left corner or by pressing the Super key (usually the the key with the Windows logo). I see previews of all the open windows (in the current workspace) in Activities overview. But I wish to see only the windows that are not minimised in the overview.
How can I achieve this?
This can be achieved using a GNOME Shell extension called Hide minimized by danigm . This extension hides all the minimised windows from the Activities overview.
