This is a HUGE waste of space on my screen. A lot of us have MacBook Airs, iPads or netbooks. On these screens that banner is a huge waste of screen real estate. In the calendar screen, for example, when I expand categories or locations on the right, I can only see three options at a time. Maybe you could have an option in settings for compact view vs. expanded view.
