I am currently using IDEA 6. One of things I think IDEA lack is the drag and drop support for JSF and Struts. I have used IBM RSA before and was really impressed by its drag and drop support for JSF. I couldn't find any plugins either which would add the same.
Afaik the same is not available in IDEA7. Are there any plans of adding it in future or through a plugin. [ November 07, 2007: Message edited by: Amit Wadhwaa ]
Currently we don't have any definite plans to support WYSIWYG design for JSP and Struts. In our experience, WYSIWYG works well only for very simple cases, and for most real-world tasks editing code directly is still necessary.
