I have been setting up more and more wireguard endpoints for myself. On the most recent, I actually have a desktop environment. I want to control the vpn status from the graphical environment. I use Devuan Ceres and they dropped wicd just like Debian Sid did. I switched over to ConnMan, and so I investigated connman-vpn, but it doesn't have anything to do with wireguard, at least not the version in Ceres. Debian Sid's connman version is 1.36-2.3, and a quick Internet search shows that ConnMan supports wireguard starting with 1.38.
So I wrote a quick and dirty shell script utility that uses mktrayicon. I chose some very simple icons, stylized lower- and upper-case letter "V." I got the icons under a linkware license: https://visualpharm.com/free-icons/v-595b40b65ba036ed117d4d2e.
Here's my file /usr/local/bin/vpn-trayicon

So when I right-click the icon, I can choose "vpn on", "vpn off", or "quit". That's about it.
