I don't think this will ever come back, mainly because MS is moving away from sliding screens to hamburger style menus in every app. This is the UI style they have decided to go with and slide to view camera roll is "counter intuitive" in that design language.
Didn't they say they are going to bring back sliding screens "where necessary" in project Neon?

The slide to the camera roll was alot smoother and intuitive. Touching that square is no where near as fast or smooth as sliding to the camera rollMaybe I'm missing something here... I had 7/7.8as well, Lumia 900. While it was "useful", we now have to tap on a square that takes us to the same photo roll. I'd prefer they get the bugs worked out rather than worry about a trivial, no matter how useful, feature. I can hit the little square, it ok. That's just my opinion though.
