This plugin adds one simple feature, it adds a filter to the content browser so that is shows unused assets, it is that simple!
Other solutions for this problem include complicated user interfaces, migrating project or running some complicated scripts. This approach integrates it into the familiar Content Browser where you can order, search, add other filters, sort, drag and drop as you usually do.
Select the filter in the Content Browser: Filters -> Other Filters -> Unused Assets
