This is useful for finding mods that are causing an error and preventing the game from launching. This can be useful for people who have thousands of mods and don't feel like searching for the cause of the problem. It works like this: someone encounters an error and has just downloaded mods for the game. The likelihood of remembering the name is slim. If they were looking for them, they might know them. When the error appears, they go to "Sort." There are already several tabs there, and the user clicks the new "Recently Downloaded" tab. They can see what they've recently downloaded and delete the ones they just downloaded, saving them hours of searching.
