here are 9 records, and 8 are displayed per page. See screenshot.
The >> is a fast forward button, not a last page button. It jumps by 1000 rows, and is disabled unless there are 1000 by which to jump.
This is counter-intuitive. If the "fast forward" is really necessary it should be configurable (jump amount) and should be in addition to a last button.
Or, at the least, the fast forward should jump to last when <1000 records.
