I've got to say SteemWorld by @steemchiller the best things I have used as a noob.
If you don't know what it is, stop reading this now and go check it out.
Put this in your browser https://steemworld.org/@yoursteemnamehere obviously replace @yoursteemnamehere with your steem name.
It has a Voting power adjusting tool, voting history, vote for witnesses, account balance, delegation start stop tool, list of followers and much more.
It is THE swiss steem army tool everyone should have!
I always have it open in another tab.
