Eclipse Mylar
I was pretty buzzed to read about a new plugin for the Eclipse IDE called Mylar, this tool largely allows the IDE workspace to be organized depending on any given task a developer is working on (from a task defect tool such as JIRA or Trac etc). When a developer is assigned a task then the IDE organizes files, resources and other items that are related to that task. This is very cool because it means that the IDE puts its self in a ready state for you to start work on your task.
