It would be nice if the PHPed IDE could offer such features as the Adobe's freeware plugin for Eclipse IDE which makes Javascript fully integrated : code completion, code folding, syntax highlighting, error reporting, and even debugging features... Since debugging has to be checked on every kind of browser (ie IE, FF, Opera, ...), this could be avoided but all the other features are a must when your seriously develop web applications. I'm even ready to give a hand to integrate such features if you'd like me to.
