Gmail and tracking numbers

Hunting around for UPS, Fedex,USPS, and Japan Post tracking numbers in Gmail is no fun. I really wish there was a way to aggregate all the shipping numbers in a single Gmail plugin which would at a glance tell me where all the crap that I ordered is at any given moment. Google already knows how to tell a tracking number from all other strings, and there are apps for iOS that aggregate tracking (unfortunately you have to manually type in all the tracking numbers). A Gmail plugin that would keep track of tracking numbers would be great – maybe anyone with a bunch of mythical %20 percent time at Google will implement this…
