Restore systray minimised RDM by clicking on pinned icon

This suggestion is one of those "nice to have" features. If the main interface of the app is minimised to system tray and there are no active RDM windows open, clicking on a pinned-to-the-taskbar icon for RDM should restore the main window from system tray. As it is, clicking the RDM pinned taskbar icon, while the main app is minimised to system tray, does nowt nothing.
