I think that on top of resource managers and project managers being able to see summary info about a user's time (Resource Management > Planner), such as Available hours, Budgeted Hours, Planned Hours, Actual Hours for a particular time frame, it would be nice if the user themselves would be able to see that overview - just about themselves, not any other User. That way they could quickly help resource/project managers in rectifying issues if they see any or even feel a bit more privvy to what their calendar will look like in the future ("I'm actually not at all available in February but it says in Workfront that I am" for a simple example of use case).
