I like steemstats very much. Some things I would like to see in the future are:
- Curation penalty calculation when voting within 30 minutes
- Follower stats, so you can see how many more you got per day, like what steemwhales has.
- How long after the post was created the upvote was made. It now sais how long ago the upvote was made, but it would also be interesting to see how long after the post it was made.
