Observation :
When I minimize the app I still have playback control via mouse-hover over the taskbar icon. However, if I set the app to reside in the system tray, when I minimize the app there is no taskbar icon and, therefore, no playback control.
It would be nice if the playback control icons were there when I mouse-hover over the systray icon instead of a tooltip-type message appearing. Is there a way to have both, or do I, for now, do without the systray option and create a wishlist item for this?
