There has been a lot of buzz about Flex and Flex Builder. This is the IDE for Building Flex RIA’s and also for building pure actionscript 3 projects. After discovering the power of Flex Builder’s coding environment it was clear to me that this would be a great Actionscript 3 editor for my Flash CS3 projects.The following video will walk you through the setup that I use on all my Flash projects. I hope this will help out with your work flow. Let me know what you think.
