Comment 40 for bug 1682542

Thank you for a reply.

As a workaround I can use "Always on visible workspace" option for main window on the 1st display and switch (wide) workspaces. This will allow me to work on 2nd display, while 1st display will remain almost untouched. I am using Multi Monitors extension [0], but there is only one thing missing - a widget with sound/network/bluetooth/user properties. Almost everything else is already cloned somehow.

I like Gnome3, because it is well integrated, it has awesome launcher/dash, it is extensible, it has hidpi support, and many, many more. It is not stable as XFCE yet and consumes too much RAM and battery, but I belive it will became a standard DE in the near future. Having a "better" multi-head support will make Gnome a winner, even comparing to macOS. I'd like to see such feature built in into Gnome, without any hacks and workarounds. Fingers crossed.

I can't say anything about technical issues or EWMH spec. Don't get me wrong - I'm just sharing my thoughts as a regular user, not a developer.
