What is the Task-Focused UI?
When you activate a task, Mylyn automatically maintains a task context by monitoring your interaction. The task context provides a predictable degree-of-interest weighting of the relevance of the elements and relations that you work with to the task-at-hand (as described in the Foundations of Software Engineering conference paper). The Task-Focused UI is the mechanism by which Mylyn presents Mylyn the task-context model in order to reduce information overload and to automate the manual management of UI elements like editors and change sets.
