We added visual feedback to the like/dislike buttons so users could know how many likes/dislikes a poster has acquired
In response to an evaluator's point, we used alternating column colors in the calendar view to set the days apart but this was not visually appealing so we discarded the idea.
We contemplated moving the calendar to the bottom alongside the buttons for switching between view modes but the calendar would have made that panel occupy too much vertical screen estate. We also contemplated moving the view-switching buttons to the left with the calendar but the similar view does not need a calendar and such a grouping would have been inconsistent between views. Finally, we considered doing away with the calendar entirely since most users would be looking for events around the current date but we decided not to because it would make event management very inefficient for people who put up events weeks or months in advance and wish to take them down or view them.
