This is really awesome and clean WordPress theme. The best part about this theme is the customizable sidebar. You can drag & drop each box to rearrange the way you like or simply collapse it to hide the content you don’t want to see. It will store the state of each box in a cookie, this means it will remember your preference next time you come back.

I am considering to pick that for my personal blog. Have a look and you will also like it.
