Yes, that worked.
Thanks.  8^)
Apparently no ill effects.

But if I then it try to start it via Applications -> Settings -> Connman Settings, I get a second instance of Connman on the panel.
I don't think (?) it should work like that.
ie: it should not be possible to load a second instance.

That said, I found the Settings menu entry connman-gtk.desktop in /usr/share/applications/:

:~$ cat /usr/share/applications/connman-gtk.desktop
[Desktop Entry]
Type=Application
Exec=connman-gtk
Name=Connman Settings
Categories=GTK;GNOME;Settings;X-GNOME-Settings-Panel;X-Unity-Settings-Panel;HardwareSettings
Keywords=connman;network;settings;wired;wifi;wi-fi;bluetooth;vpn;tethering
X-GNOME-Settings-Panel=connman-gtk
X-Unity-Settings-Panel=connman-gtk
Icon=preferences-system-network
:~$ 

Thanks for your input.

After upgrading to Daedalus I am slowly finding bits and pieces which are not where they should be.
ie: where I expect them to be, which is not the same thing.

In Beowulf, with the now abandoned WiCD, I had the application's icon sitting on the xfce4-panel.
One click away from switching to and from my available WiFi / wired connections.

Quite handy when one of them has a problem ...

Now, in Daedalus and with Connman, this should also be happening as it I have configured it to work that way.
ie: Applications -> Settings -> Connman Settings -> Settings = Use status icon [x]  and Launch to tray by default [x]

Not the case.
The icon only shows up if I start Connman from the menu and stays there till I either close it (right click -> Exit), restart the desktop or reboot the system.

Looking around, I found mention of this in a GitHub thread thread from 05/2019.

It would seem that what is needed is for Connman to install to autostart and not to the Applications -> Settings menu or maybe to both (?) and it looks like there was a patch/commit issues but ...

Would the solution be adding Connman to ~/.config?
Would it coexist peacefully with Connman Settings ?   

Please advise.

Thanks in advance.

Best,

A.
