TM Watcher for Trademe.co.nz
TM Watcher checks auctions in your Trademe watchlist to see when any of their attributes change, then notify the user. This includes attributes like bid price, end date.
I've put alot more polish into this than ODW, it feels good. I figured out how to have it run something at boot, which has the effect of greatly simplifying the user controls improving the user experience, compared to that of ODW. I even got a friend and did some user experience testing :)
