Thanks @fitzgibbon!
Sortable columns is definitely somewhere at the top of our to do list, so we hope to introduce this soon! This will also enable you to sort on the highest upvotes you got, so your first suggestion might already be merged in that case!
Also, I would love to have insight not only on my followers, but also on the ones I follow -> what was their last published post, how many upvotes did these get, which rewards... etc
What made you think of this :D Curious to know as to how this information would be different than your feed on Steemit itself.
What we did have in mind was to show some more generic data about the people you follow: who are do you follow who are dead (so you can unfollow them and on who have you been voting etc.
