In the new Planning tool when filtering to "View by User" it would be great to see a row of "Unassigned" planned hours. This will allow us to plan for capacity on a monthly or quarterly basis in the future because we don't typically assign/schedule specific people that far in advance. I see this being most useful as we plan and manage our upcoming Scope of Work at the beginning and then throughout the year.
Example view with Unassigned row added:
The Scheduling tool allows you to see unassigned tasks but you're not able to zoom out to the month or quarter. Even if you could do that, I don't think it would make sense in the Scheduling area because it's a resource planning exercise, not actually assigning resources.
