Very cool stuff ! I've wanted to have that for some time now. Are you sure about the conversions ? some other websites like steem.rocks give a way more conservative estimate.

edit : I realized that it shows the total rewards not the rewards that the author gets.

Although I kinda dislike that you have to click on "reward" to get the value, it would be better to just set the price clickable and then if you click on it you get the sbd/steem value no ?
