Plugin > LiveTraffic > Aircraft Info... (Popped out) for creating a popped out window in a native operating system window, which could be moved anywhere.
It makes most sense if you have and use for this purpose a monitor, which is not filled by X-Plane, e.g. if you keep one monitor for flight planner, moving map or the like. Otherwise the popped out window would become hidden behind X-Plane once X-Planes gets the focus - just like any other window as well.
The initial position of any new window might not be optimal and you might need to drag it out of a corner to see it completely.
