System tray icon
Most communications programs have system tray icon support. This is specially handy for users of multiple virtual desktops. Other similar programs such as Kopete, Spectacle and Pidgin have system tray icon support. Some (just me?) view it as a essential feature for a chat application. Please consider adding system tray icon support. Do be aware that it would have to be optional as that foot desktop environment does not have a system tray. All other desktop environments (KDE/LXQt/Xfce/IceWM/Fluxbox) support a system tray icon.
