That's a good point. I put it at number one because I knew it was the first thing that would be noticed anyways and would only take a couple seconds to show. While I believe it is an improvement I wanted call it out to help manage the change (as any change can represent friction). Probably the end would have been a more appropriate place.

Many other places showing what has changed in 1.5 have the "top ten" feature list in more of a priority order in which I put the icon change in the last position. The video I made as more of a comprehensive guide to the changes for our existing users than a highlights video. Ordering in many cases was somewhat set by the features themselves; for example it is hard to show of smaller feature of the new animations timing functions without first discussing the more significant redesigned animation interface, etc.
