The plug-in is easy to install, and it has a couple of nice features like syntax highlighting, support for Javascript libraries like Dojo,Prototype,YUI,etc and code completion. One feature I like a lot was the templates feature where you can create your own code templates. This plug-in used to be part of InterAKT but Adobe acquired the company recently, and they release the plug-in for free.

I really like what Adobe is doing for the community, as well for the new technologies they are developing like Apollo, which I think will be a killer technology.
