Flash 2004 Extensibility / JSFL Docs release
We have released the complete docs for the Flash MX 2004 extensibility layer. This allows you to script the authoring environment and create news tools, commands and extensions. I personally think this is the coolest and most useful feature of Flash, and I have already used it to create a command line compiler for the authoring environment.
There are a couple of extensions on DRK 5 which use the extensibility layer, and you can also see a list of third party extensions here.
You can view the docs on-line here.
Have you had a chance to play with the extensibility yet? If so, post your thoughts and / or links in the comments section.
