We've all said to ourselves at one time or another, "man that's a good idea, but there's some bugs to be worked out. I want to wait to see how it develops." I emailed Sam at aTrackDog with this idea combined w/ a donation and he said he'll maybe try to add it in an update. The only hassle I foresee, is that we'll have to manually add to a "watchlist" the apps not currently installed for which we want version tracking (because I think we are restricted from adding let's say a long press option to the market). If we could do that, then it probably would not be difficult to add an app search "wishlist" for apps we'd like developed or are anticipating a release. Just putting this out there in case someone gets ambitious.
