The "blob" was a hidden and undocumented interface to Exposé that was discovered by a member of the MacNN forums.<ref>{{cite web | url=http://forums.macnn.com/showthread.php?t=181452 | title=wvous: 'Hidden' Dock Feature | date=October 9, 2003 | author=sandsl | work=MacNN forums | access-date=August 20, 2006}}</ref> When clicked, it enabled the "Application Windows" mode. When Option+click, it enabled the "All Windows" mode.

Another undocumented feature of Exposé was for the show desktop function. It placed all the open windows in a small box on the screen that can be moved to anywhere on the screen.<ref>[http://www.macosxhints.com/article.php?story=20031028081746219] Tutorial at macosxhints.com</ref> This function had some bugs, such as after exiting the show desktop mode, the foremost window will not have a shadow and the user will not be able to move the window. However, this was easily fixed by using the show all function. It also had another bug that causes an area of screen the width of the minimised preview to become unresponsive to mouse clicks requiring the windowserver to be restarted.
