Looking for “see also” plugin

Hi,

I’m looking for plugin to solve my problem. As I guess this is common case, I believe there is a plugin already made for this.

Plugin should do this at page-editor:
– there should be a box at sidebar, where one can select “see also” -pages.
– At selection box there’s drop-down -selection for whole menu structure.
– As one has selected a page for “see also” -selection, this page is added (AJAX or something) to the list, and one can select another page.

At theme-level:
– See-also -links should be delivered as an array-variable for single page. Then they could be rendered as page designer has wanted.

Is there such plugin available?
