Installer.app 3.1 Adds Ability to Filter Application List

Installer.app now includes a filter bar that allows you to type text and have the list of applications filter to only include those applications that have the text that you type in the filter field.

It looks like it is a search bar; however, your do not have to click a search or "go" button. The list automatically filters the current list as you type text into the field. The Filter bar only appears once you select a category of application or only when a list of applications are listed.
