Now, one page content will be changed after Clicking
"Next page" or "Prev page" to go back.
As we know, the order of the list could not be changed
at will, for one at the beginning or the end is a marker.
The marker is very importent for pagination.
So, this commit remove the sort of snapshots and reverse
the sort of the previous page ones.
