I am liking the changes to 14.1 overall but I noticed something different with the way 14.1 handles Maven projects.
It use to be where when I am finished working on a Maven project that I would go to the "Maven Projects" window, right click the module and do a remove. The source code from the "Project" window will also be removed. Now, removing it via the "Maven Projects" window does not entirely remove the module from my project.
