Viewer for all users free/busy info
A viewer (Gantt chart-style or ?) that allowed someone (like a receptionist) to view all (or filter certain) employees to see whether someone was in the office or not, or tied up in a meeting would be helpful to be able to quickly monitor employee availability for phone calls or other needs. This would be almost exactly what shows when you use Scheduling Assistant when creating a meeting with multiple users, but without having to "create" a meeting to view this. Preferably this would be an online tool to avoid syncing issues.
