Resurrecting this really old thread to add my thanks as well
I've used at on of IDEs and didn't really like any of them. FD is absolutely amazing and all the stuff I've come to love in Java/Eclipse is there in FD.
Yesterday, I moved about 95% of my work-flow into FD. No more Flash CS3 for me!
I've made my $30 donation, with more to come if I can get a game sponsored by Flash game portals
Huge thanks to the FD team!
