There are a number of cool new features coming in SpringIDE 2.0, currently at milestone 3. One example is the new SpringExplorer, which is a comprehensive tree view of a Spring context, another is content assist for custom namespaces.
But the by far neatest new feature is the ability to evaluate AspectJ expressions in XML on the fly, and displaying what beans will be advised! Take a close look at this screenshot...an <aop:advisor> element is highlighted on the left, with an AspectJ pointcut expression. On the right, you can see what methods will be advised (the "advises" arrow). A godsend!
