Unfortunately the only change that I like is the ability to customize the bottom navigation bar on the mobile app to hide features I don't use (Notes and Files). The new selector and emphasis on Gravatars is disappointing; I understand the logic behind using a Gravatar, but it is a service that basically has photos of my contacts from the early 2010s, when it was most relevant.
