I wasn't around when jewelry engraving was around, but
it would be neat to see that come back. Also, having the header
bubble say "You have x Profile Comments" instead of just "Notifications"
It's not a Gaia feature, but I also really miss some of the friends
I met on here that left. Out of the large group of friends that used to be
here, only about 3 or 4 remain.
One thing I don't miss is the days before multiples of an item could be stacked into one icon.
