The web site has been updated with screenshots from the forthcoming version 1.5. We've also added extensive information about the new Route Filter feature. We expect to submit version 1.5 to App Store in the coming week.
What's next? The three main things we have planned are to add an iPad version of the interface, to get ready for iPhone OS 4.0, and to add maps, probably limited at first to state highways. There have also been some requests to add Push Notifications to CHP Traffic. However, before that can be useful, we'll need to find a way to convert the vague CHP descriptions into concrete map locations -- the same thing we need to add map support for all incidents.
