Hello, Just upgraded to FF4 and discovered app tabs and tab groups - both great features. However, when I switch to the view of my tab groups, I don't see the app tabs shown anywhere. They aren't in the default tab group, nor in any of the tab groups I created. If I right-click the app tab, there isn't an option to put it in a group, and if I right-click a tab in a group and make it an app tab, it doesn't show up in the group any more. Any way around this? I like both features, but would like to group app tabs as well as non-app tabs. Thanks
