Agree. I have no idea how many I've downloaded (to check for cheaters, mistakes I made etc.) and then... I can't find it the day later. Because there's no tab. They might be eating up gigabytes of data on my hard drive and I have no idea where they are.
I mean I could google, but rather it be an in-game function so I can delete the ones I don't need or want to see again and keep ones for later, like any video.
