Bug 465875

My workstation has 3 monitors. I have a panel on each monitor display area and I run task manager in each panel. I have each task manager set up the same:

- Group by program name

- Show textual list

- Combine into single button

- Show only tasks from current screen, from current desktop, from current activity.

I run multiple virtual desktops.

Recently I have experienced issues with KDE 5.27 beta getting the monitor setup all mixed up when disconnecting a monitor and reconnecting it. Between this and crashing issue with Firefox, my Firefox windows get shuffled to various virtual desktops and displays.

Resorting the Firefox windows is a pain especially when a bunch of them end up in the panel on the wrong display. When that happens I have to open each window individually and drag it to the correct display.

Right now Task Manager has the option of Move to Desktop to move a window or group of windows (if grouped by name) to a different VD.

I'd like the same thing for moving windows to a different display. So if a group of 20 Firefox windows gets moved to the panel on my side display, I can right click the group in task manager and move them to the center display where they were before my monitors got messed up.
