Windows opened by QJackCtl aren't shown in the panel
This project https://github.com/rncbc/qjackctl opens 2 windows: its main window and one with Jack topology that is opened when the "Graph" button is pressed.
Both windows aren't shown in the panel. Not as regular windows, and not as tray icons.
As a result it is difficult to tell if QJackCtl is running. The user needs to minimize other windows to see if QJackCtl is anywhere.
