While I was fiddling with the RD, I noticed something about the seat-stay on the drive-side. It has a little metal tab, and there's a flatish spot underneath it. Can anybody tell me what it's for (or what to use as a google search term)?

Are you referring to the chain holder? That tab on the drive-side seat stay holds the chain up when you are removing the rear wheel.
