Flash MX 2004 Pro has a new feature that will have traditional developers salivating, and it's called Formsbased Development (also known as Screens-based Development). This new offering will also prove valuable to those of you who have never set foot into the wild world of traditional development.
So what is it? Simply put, it will enable you to structure complex applications in Flash without using multiple frames or layers on the main timeline. Instead of basing your applications on traditional timelines, you'll be able to visually lay out your application as a series of screens. But don't worry - you'll still have the choice to use the timeline or a mix of forms and timelines if you want to.
