I have published a review on FDT 3 for Eclipse. This application is a wonderful ActionScript editor that when paired with the Flash code library makes it very painless to develop Flash applications.
The latest release has support for ActionScript 2 and 3 which is great considering even the latest version of Flash still has an integrated editor that needs help.
Once I get a few moments I will be writing up a few tutorials for FDT.. this of course will be after I have completed my Flash and PHP Bible.
Update: FDT has linked to this review, pretty cool!
