Sometimes a small change in an application can make a pretty big difference in user experience. A colleague of mine installed the NetBeans IDE 7.2 yesterday. And after a while he commented that you can now select multiple Maven-based module projects and choose the build action from the context menu! It might seem like an insignificant change, but with our 3-tier application a change can often stretch over multiple modules. So for us this is definitely useful!
Do keep in mind though that the multiple builds are started in parellel. So if there are dependencies between the modules you would still have to choose the build order yourself. 🙂
