Gantt Chart Status Rollup & Filtering

Currently marking all sub-tasks in a Gantt Chart as complete does not roll up to summary tasks.  Put differently, summary task status does not inherit status of sub tasks.  In MS Project, marking all sub tasks as complete will roll up and leave the summary task indicated as complete as well.  It would be great if Wrike implemented this.

Similarly, when filtering a Gantt view by status, there is no opportunity to indicate at which level you are concerned.  If, for example, you had a summary task with four sub tasks, two of which were marked as complete, then when filtering for active tasks you would see the summary task and two incomplete tasks, but not the two completed tasks.  If a summary task is not complete then it should be possible to view all sub tasks irrespective of their individual status indicators.  The reverse is true as well.  When filtering for tasks with a status of complete, sub tasks belonging to a summary task that is not yet marked as complete should not be displayed.  Or it should at least be configurable.
