Workspace suggestion

I'm having a problem with the workspace for this lesson and it occurred to me that it would be very useful if the index.html file that appears with the workspace when it's created came with a start and final version of the code that its going to be created in the lesson. My problem is that is I make a mistake when writing the code, it gets highlighted in red and becomes very difficult to see where the problem is. I'm also finding that when I'm writing HTML tags, I'm seeing a lot of random </h1> tags being created where they have no purpose and this just adds to the problem. It would be nice if I could go back to a clean starting point and redo what I've done or look at a completed version and identify where I've gone wrong
