I'm not saying that we should do this right away, but it seemed like a good idea to suggest.
I find it hard to visualize the shape that my story is taking, so to help me plan the story more efficently I've been using MS Paint to create a sort of "tree" with branches that represent choices in the story. I kept using this model in MS paint when it hit me, what if the site itself offered this? (BTW this is another one of those late night ideas, no worries if rejected.)
