The standard page navigation in the admincp consists of...
on the first page:
[Next]
on subsequent pages:
[Prev][Next]
on the last page:
[Prev][First]
so, you are stuck going sequentially and cant jump to the end.
when i say consistency for this case, i meant consistency with vbarcade

since the technical restrictions (and performance implications) on the import process dont allow me to get a consistent number of results there, thus i came up with that, plus i never liked the restrictive vb version. with mine:
on the first page, and subsequent pages
next page: default current+1
[Continue]
That makes Continue, by default, act as Next. You can jump back to first page (with page 1) or any in between by typing in the desired page. when i said back button, i meant the one on your browser, which is thoroughly understood on how it works (even if the backspace one isnt).
Again, I fail to see how my version is hard to use or confusing; we are just arguing over which thing it should be consistent to.... in which case i definitely like mine better, because it overcomes the limitations of the old one, but is still one-button for the most common action (Next).
