Widgets, Gadgets or Modules are very common and powerful feature of Web 2.0 applications. They convert a single loaded page in the browser to multi-threaded application.

They allow end user to work on multiple little utilities and windows from one page. The widget framework is supported by various Ajax libraries and lot of code is getting created by developers to allow this feature.
