Wireguard VPN plugin for NetworkManager from https://github.com/max-moser/network-manager-wireguard/. It's incomplete, not very elegant, and has some flaws. But if you want to try it anyway, here it is. It is only available for F28. It seems to need some modifications for newer NetworkManager versions on F29 and later for which I do not have the time.
