The typical design for a paging panels (of search engines and the like) looks like this:
Previous 11 12 [13] 14 15 16 17 18 19 20 Next
But if you read that you would expect (if not educated by search engines) that "Next" will lead to the successor of page "20" and not of "13". If we need "Previous" and "Next" at all, wouldn't it be better to place it, where their meaning is obvious?
11 12 Previous [13] Next 14 15 16 17 18 19 20
or maybe
11 12 < [13] > 14 15 16 17 18 19 20
The question is: is "Previous" and "Next" really useful and if so where to place it?
