<p>Just a little widget that adds in some useful functionality that WordPress (oddly enough) doesn’t include stock … listing almost all of your categories. Say, for example, you have a utility category entitled “Events,” and you want to display a list of all your site’s categories, but don’t want “Events” to display in that list. Instead of hard-coding a list into a text widget, just use this!</p>


Almost All Categories Widget

This widget will let you display a category list in your sidebar, excluding any categories that you would like.
