Thanks for all the great suggestions. I used IntelliJ at a previous job and loved it. Unfortunately we're a MS house here and I doubt I could get the request approved. :)
I'll check out Aptana's latest as well as Spket. I use Notepad++ for quick and easy edits so that's my general text editor of choice. Thanks to those offering similar solutions. I'm looking more for an IDE that can understand the link between several js files and assist with intelligent Intellisense / Snippet like features. If anyone else has others to offer keep them coming! Thanks, Matt
