I am using Ubuntu 18.04 with GNOME. I would like to know if there is any functionality that allows to associate multiple windows in such a way that when one of the windows is minimized all the other are too and when the window is restored all the others too.
I.e. I am working with multiple terminal windows and I would like to group the terminals in N groups, in such a way that when I minimize a terminal window all other terminal windows that belong to that group get minimized too.
