Nice to have against the Close or Save button is a beautifull Cancel button. A request of a customer this week was to have a link on there intranet to a sharepoint custom new page, but without the Sharepoint header and menu. So people could add items in a list, but nothing else more. On the page the Sharepoint Close/Cancel button returns automatically back to the Sharepoint List. But what the customer wanted was that the requester returned back to the page where they came from or, if the page was openend in a new window, to close the window. To do this, replace the Sharepoint Close/Cancel button with our own custum buttom. add a little script in a content Editor webpart to execute the return function (goback).
