It's very convenient, I wish I could offer a worthy suggestion. The trouble in my case is that it's very sensitive and the palettes are barely in view before the page refreshes, they don't reach the center of the screen. Thanks for sharing

The problem, from a UX standpoint, is that you need a visual affordance for the behavior. That is, you must indicate that it's about to happen and give the user the opportunity to abort. Alternatively, a continuous gallery could suffice.
