JackWidget is a multi-purpose search tool. It provides quick access to dozens of commonly used web searches.

JackWidget has a search field and a popup menu. The search field, of course, is for typing in the search. The popup menu is for selecting which site or sites to search. Some of the popup items actually send your search to several websites at once. It's as easy as typing in some search terms, choosing a search from the popup menu, and hitting return. The widget activates Safari and executes the search(es). It also supports command line interface style usage, allowing the user to bypass the popup menu. It has over two dozen searches built in, and is infinitely customizable (if you know how to open a widget package and edit XML files).

Requirements:
OS X 10.4-10.6
Universal Binary
