We've quietly put up a new AJAX version of the Airport Summary online for users to play around with. We haven't announced it on a grand scale on the home page yet because we're still tinkering with it considerably; and since it IS still in early BETA, there are no doubt going to be issues and troubles with it. But the concept is pretty cool.
We're planning on moving the site and its functionality towards a more "control center" approach, where users can quickly access the various features available, arranging windows as they see fit, instead of trying to structure everyone through numerous menus every time they want get an overview of their flight tracking workscape. The new Summary is a step in that direction.
Stay tuned as we continue to tinker...!
