Please add connman-ui to portage. From the README: A full-featured GTK based trayicon UI for ConnMan. It targets all WM/DM users but Gnome3 ones*. It works on any Linux WM/DM which provides a freedesktop compliant system tray. (kde, awesome, ...) It exposes almost all features provided by ConnMan API (small features are missing, see TODO for more information). You can enable/disable a technology (wired, wifi, cellular, bt, ...), connect/disconnect a service, configure a service (IPv4, IPv6, DNS, Timeservers, etc...), share your current connection (tethering) and so on. Everything is accessible through the mouse via the trayicon, all with left and right click. Reproducible: Always
