It's awesome to see great apps thriving on this blockchain.
Regarding what I like most about esteem is the fact it you can schedule posts, I think most front ends should have this implemented in one form or another.
What I would like to see in the future is better integration of video and images so that thumbnails are actually displayed in the feed so the message that there is no thumbnail shouldn't appear without it being the case. Also I would love to see a tipping mechanism like dlive has implemented in order to reward valuable old post post.
