Wow. I actually wrote down the ideas im going to implement when I redesign Steemit. Here they are:
TODO:
-Onboarding process - earn your first SP
-Notifications
-Working chat
-Switch layouts
-Dark version
-Compact header
-Favorite tags/categories
-Better secondary menu
-Tags = groups
-Better editor
-Working search
-Not upvoting your own posts
-Website should explain how to vote and what it means
