Customize Widgets

This plugin adds an additional admin page which shows you every registered
widget, and allows you to deactivate any you do not want to appear. For
example, when you are adding widgets to a sidebar, the Post Loop widget is
usually not wanted, and just adds additional clutter you must sort through. On
this widget’s admin page, simply click on the widgets you would like to
disable, and then hit the “Save” button at the very bottom of the page!
