Scrap
Have you ever felt tired of selling, over and over, all that items you don't need at the merchant? There are several addons that lets you create a "junk list" and sell all the junk in your bags with a single-click, but they are always hard to use and doing the simplest tasks, like changing their filters, can be a real pain. Scrap tries to fill this hole: it is designed to be an easy to use and intuitive addon, but lightweight at the same time. If you are tired of slash commands and hard configuration, then this is the addon for you!
