SUMMARY The contextual menu that opens when you right click on some application title bar includes a "Move to screen" entry. It would be great to also have it on the contextual menu that opens when you right click on some application icon in the task manager. Rationale: there are some monitors that may remain black when some setting is incorrect, or that might take a long time to get out of sleep, or that may remain black due to some intermediate element (e.g. a KVM switch). If an app is on a black screen, it is a pain to move it to the main screen, because you cannot drag it. Being able to use a contextual menu from the task bar would help.
