The calendar views are pretty limited, making it difficult to utilize calendars, especially multiple calendars, efficiently. I'd like to see more flexibility in the existing calendar views. If I could get only one improvement, it would be allowing the 'all day event' region of calendar views to be expandable via drag and drop (or if not that then customizable via a setting). The area is unnecessarily puny now. This should be an easy fix/win. Related to this, the 'X more' popup is teeny. Ideally this floating interface element would be expandable too.
