Change the color of the red button "Disconnect *server" in top section of the App.
The red color is usually associated with disconnect and often implies something is wrong. Subconsciously, every time I look at the App window, I suppose the server got disconnected or something's wrong. It gives me a sort of a false alarm and sense of a problem(instead of security). The VyprVpn's menu icon and dock icon have avoided this problem.
or perhaps have the red 'disconnect' bar be an octagon, as in a red stop sign.
