Well i went to put some glados into my map, and have found that not only can you not preview the sounds, but that its quite hard to select the one required based on filenames. So im thinking of making a list of glados lines and their corresponding file names. Would this be worth doing, or has someone done it already? (in which case please send me a link!)
