Task Focused Interface (like Mylyn) for NetBeans IDE

Project NBTaskFocus makes the automatic tracking of your opened editor files available in its alpha version.  It provides two panels named 'Task Explorer' to see your tasks and the activation state of the task, and 'Task Details' to see your tracked opened file context.  As soon as you open any file in editor of NetBeans IDE it is added to the activated task as its context.  If you close an opened file it is automatically removed from the context.

The article on NetBeans Zone describes steps how to use the NBTaskFocus project.
