The Model Focusing Tools project brings Mylyn's task-focused interface to modeling tools:
Diagram editors, such as for Ecore and UML models
EMF generated editors
It provides a focused mode for diagrams that shows only the elements related to the task-at-hand, dramatically reducing information overload when working on large models. In addition, the task-focused interface extensions provide Mylyn’s one-click multitasking facilities for working with models, ensuring that developers can instantly recover from interruptions, and share model-specific expertise.
