I'm still curious what IDE you used for your project

I use Netbeans, it does not get a lot of press but they have been outpacing many of the dedicated JavaScript IDE's they have great JavaScript support.

how do you rename a method for example with the tool use (imagine that another method with the same name exists in a different class/module)

I use Dojo for large JavaScript projects, there really is not an alternative when you get the the application sizes I deal in, as such everything is namespaced. Netbeans can refactor methods in JavaScript, so I use the built in functionality of the IDE to do so.

I have a colleague who uses Netbeans for Javascript so I took a look. And yes it looks better than the default Eclipse editor for Javascript (the jQuery auto-completion is quite interesting). But still it's not working in many situations, unlike the Java support that works all the time.

Did you add jQuery support through the libraries? or did you just add it in your project, I have found auto-complete works a lot better when you explicitly add the project to Netbeans via the libraries mechanism.
