I've been using Gnome 3 and while I like the simple panel design, I have not been able to edit it. I run a VPN client and I cannot access it because it uses a tray icon to change the settings. In Gnome 3 no icon shows up, but the VPN still connects. I've searched and most people say to press alt + win + right click to edit the panel but I've tried all kinds of key combos and nothing happens. I only have the default drop down for the volume, wifi, and power controls on the right.
