I have paid for a lifetime subscription to VPN Unlimited, so would like to use it on my Elementary notebook computer. Unfortunately, while it does appear to run correctly, I can't get it to do so in any mode other than w/its program window displaying. Yes, I know, I can move it to another desktop. But, under Windows (and other linuxes), you can close VPN Unlimited's main window and the program will minimise to the notification area.
I Googled a bit, and found the page below, but doing as directed did not solve the issue. Any idea of what I can do to get VPN Unlimited to minimise to Wingpanel?
