I've been testing custom stories in the latest beta (0.16.4) and noticed a couple of things that I'm hoping you're planning to handle in the stable release. None of them affect the Original Story, though, so in case they're not on your list, I figured I'd point them out and cross my fingers.
First, there are no inventory images for: phone6, the sunglasses, or the red solo cups. I really like the improved inventory system, though.
Also, makeout sessions between the player and the new improved Amy are horrifying. The view from inside her head is so... toothy.
