Usability tip: I would not have the Hi there box in the main panel. Maybe have it as a popup? Keep the main area clear.

Else, the first thing people try to do is find a way to close/remove/delete it so they can get started, which leads to the down arrow on it, which doesn't work to delete it. And now they're stuck wondering how to delete it...then they close the window without even tasting something they may have enjoyed.
