Enable filtering in Project Formation

When viewing a specific project > Overview there is a filter bar presented so tasks can be filtered by such things as Label, Category, Solver, State, etc.

However, when viewing the project on a different tab (e.g. Files or Process) the filter bar is not available. Thus, for example, I can't filter on the Process view to see only ToDo tasks and hide tasks that are completed.

Please carry over the filter bar to all project views.
