Project tasks display retained

When a project is opened, all of the tasks - both parent and children - are displayed.

For ease of use while using the project, some of the parent tasks are collapsed which works well in the current session.

However, in the next Workfront session (ie: next time one logs in), when the project is opened, all of the tasks - both parent and children - are displayed.

Please include a mechanism to retain the project display with the selected collapsed tasks.

Thanks
