#24 Consistency in feature maneuverability

[Simon Reeve]

I like the ability to move the features on the stack pages (i.e. the ability to move the sliders and the orientation window). However, it'd be good that if I move them for my own convenience, they stay where I put them when I change stacks. Currently they are set to return to their default states - I think this should only be the case if we refresh the page or move away from the stack pages.
