Before the heuristic evaluation, we put in some animation that slid in the new week when scrolling weeks but it made posters disappear briefly before showing up the poster of the new week. An evaluator thought the behavior was jarring and we removed it.
An evaluator Some evaluators pointed out that there was no way to remove a poster added in error, for instance, so we implemented this critical authentication-based delete functionality

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.
We removed the randomness in the ordering of the posters in the Similar Events View so that every time that view is brought up, posters remain in the same place they previously did.
We made the event category labels clickable to solve the problem of visibility when there are a lot of events in a category and the posters begin to overlap.
We changed the reminder icon from a calendar icon to an alarm clock icon because the calendar icon was confusing given other uses of a calendar (primarily in the Calendar View)
Evaluators thought the scribbling feature was interesting but was concerned by the lack of a way to save, erase and change the pen color of a scribble. We implemented all those features.
Some evaluators thought the 'x' used for closing the Add Poster dialog was not externally consistent or noticeable enough and that the dialog could not be dismissed by clicking outside it. We changed the 'x' to a much larger 'Cancel' button within the dialog but retained the strictly modal functionality for safety reasons. We wanted to prevent users from dismissing the add dialog in the middle of adding a poster and having to start all over again.
Hovering over a poster caused jerky behavior and we fixed it.
User Testing. If we were going to make further changes, we would make the following changes based on user testing feedback
We would increase the information scent because some users
