Steemdb.io
Here's another wonderful steem tool with a nice responsive theme. The landing page seems to be a display of recent blockchain activities. This tool also gives the history of an account activities and every other activity involving the account over the last 30 days. It's really synced with steemit, I was surprised to see even my most recent activities/transactions ready documented.
In the drop down menu, there are four tabs
witness
The witness section provides information on witnesses and their current position on the board, increases in vote as well as the url to their respective accounts. It also shows the total vote history, respective votes cast by an account to a particular witness along with the time the action was performed
Labs...
I find this section most interesting. It shows a list of current experimental pages that don't really have a home on the steemit site yet, something like a beta test. For example...I could check out the author reward leaderboards page in order to view the highest paid authors daily on Steemit, same goes for highest paid curators. Basically a steemit related search engine.
Account
It shows various accounts in the blockchain sorted by various metrics, richlist by default which includes vests/steempower, steem, SBD and power down other metrics are posts, social(followers, followers value) and reputation.
I always advice to check out the various steem tools experminent and play around in order to fully understand them as one post cannot fully review any tool. If a post actually succeeds in making a review that encompasses all elements of the tools, you probably wouldn't be able/ want to read it all.
