The My Calendar view would be much more useful if users were able to change the Task info surfaced on calendar entries. We should be able to choose to see any combination of at least the milestone, tasklist, and status in the entry. This is especially true since tasklists don't have owners and milestones can only be assigned to one user.

Doing this would make the calendar useful at a glance. Right now, you have to click the task and roll over the Task Information icon to see basic information. This is especially true if task numbers and prefixes mean absolutely nothing to your team.
