In the stock gallery app, if you tilt the phone the thumbnails tilt... is that it? Are they supposed to scroll when the phone is tilted (mine don't)? Just curious, because I can't seem to find a reason for this feature.
That's all it does. I think it's an effect added to visually "compensate" for tilting the phone. I don't use the stock gallery, though, since it's slower than a glacier.
