Additional resource filter options
Allow Users to be assigned to Groups (e.g. Departments), and allow Resource Filtering by assigned Group/Department, rather than just individual user names. This allows a department manager to more easily view all tasks for which they are responsible, across multiple open projects.
Also: within Resource Filter, allow option to select "Unassigned" tasks as a specific filter. This allows the project manager to find such tasks and make sure they are assigned.
Or just the ability to sort by Groups would be nice as well. If someone has multiple projects (groups) assigned to them or you would like to only see a single group of information along with its subgroups it would be very easy to update the larger projects
