Not sure if I didn't see it but the mobile app for Touch Arcade as a handy "watch list" that as far as I can tell doesn't exist on the full Desktop site. Also I don't see a sign-in other then on the forums. The mobile app allowed the saving of articles to users also. Not sure why this isn't on desktop.
Also! This has been recommended before but to add to that, please please PLEASE integrate Appshopper with Touch Arcade more. I really love Appshopper and Touch Arcade also and the wishlist of one should be integrated into the watch list of the other. Sister sites should be sisterly and share!
