I have created a new site called SteemDash.com. It allows you to view many helpful sites about steemit, all on one page. This is different from other sites because it has iframes that link directly to those pages. I programmed it from scratch using html. I am currently accepting suggestions, and I hope you enjoy!
Also, below the fold of the page, there is blocktrades.us and a steem voting power calculator.
As requested, here is a list of the tools on this site:
