The calendar functionality both in Campaigns, and the sidebar is great. However, there is one feature that it is lacking.
That is, emails in draft status. We often have many emails being simultaneously developed -- and determining the best send days/times to avoid oversaturating our audience at the same time other messages are going out is difficult. If, emails that are in draft status -- but have a "scheduled day/time" would show up in the calendar with a different colored icon to indicate they have not yet been scheduled/approved -- that would allow all users to see not only what has been approved/scheduled/sent; but things that are planning to be sent.
