The new version of the Safari web browser included in Mac OS X 10.4 Tiger (Safari 2.0) has new ways to open pages in tabs, particularly when submitting web forms. Merlin explains why this is cool.

Merlin mentions quickly deleting multiple items from an Amazon wish list as a use case, and while it's a valid example of web forms that inconveniently redraw everything at the touch of a button, you don't need Safari 2.0 to do this. The wish list "delete" button is just a link, so any tab-enabled browser (Firefox, earlier versions of Safari) will let you middle-click to execute the action in the background while you click on other delete buttons.
