Please make it possible to base a new project on a different maven file than "pom.xml".
After having tested IDEs with maven support for several years now, I still find that "mvn idea:idea -f workspace.xml" is the only useable integration method. The main reason for that is that I hardly ever want the module set of the workspace to be the same as the unit-of-release in maven (which is what you effectively do with a shared parent pom multi-module project). I always want to add modules with common code that is shared across several projects to be part of the same workspace, so I can adapt and refactor it.
Typically, a workspace.xml file for a project looks like this:
So, please make the maven integration up-to-par with mvn idea:idea by adding support for joining several "parent poms" together in a workspace.
