Looks better than connman-ui
Indeed, it's awesome really. Looks good, stays out of the way and it's usable when needed.
Btw, I haven't mentioned it here, I'm not the actual author.
I just packaged and patched it to enable window toggling from tray icon.
One item though, don't mean to nit-pick but on your git page you have:
GTK >= 3.10
Shouldn't connman be on the list, this isn't a stand alone application is it?
Well, it should be, though it implies itself since it's a front-end for it ( not a stand alone )...
Anyhow, it's fixed now.
Successfully compiled it on Void Linux.
I'll have to run connman for a while; much smaller memory footprint than NetworkManager or wicd.
Also seems to require root privleges to connect/roam with wireless. Will that be the case on Debian as well?
I'm using it for atleast 6 months and honestly have no idea it's even there. The damn thing JustWorks™.
As to WiFI & root, I wouldn't know since I don't have a WiFi to test ( desktops on LAN all around ).
Though ( on Debian atleast ) I am finding it odd that the "connmanctl" command is installed in /usr/sbin ( thus requiring root privileges )...
For example, on Arch it goes to /usr/bin...
With that said, you may try to symlink it to /usr/bin:
sudo ln -s /usr/sbin/connmanctl /usr/bin/connmanctl
I'm not sure that the front-end will even look for it there ( both connman and GUI might need rebuilding for this to work ).
And, after symlinking do verify that it actually works without root:
connmanctl scan wifi; connmanctl services
and then try to connect to one of WiFi's listed with:
connmanctl connect wifi_xxxxxxxxxx
