tool tips text on threads

I often hover the mouse over the number 1 underneath a post to give me the tool tips text of the post. This way I get the jist of the post and decide if I want to read it. If you hover the mouse over 'last page' you get exactly the same text at hovering over the '1'. It would be a good idea if it displayed text from the last post in the thread when hovering over 'last page' IMO.
