Code editor

[Smevy]

Now first off the code editor works great and there are no problems with it. But when you first click on the code editor there is a button that says Start Creating. but the rest of the screen besides top-bar and docs it is very blank and not much is there. I know this does not really matter just thought it might be nice to add a bit more to that spot. I have no suggestions just always thought it was a little blank in that spot
