We aren't doing this, and we definitively should! I've added this to the todo-list, and will work towards having manually curated lists up first, and try to make it a bit more automatic when we have a bigger user mass. Can't give you a specific date for implementing this, as Wishy.gift is both a sideproject and - at least for now - very seasonal (36 of the 53 new users since March signed up in November/December), but I'm hoping to have this up for August/September :)
To be honest, I wish I had this two weeks ago when I was making my own wishlist!
Thank you for taking the time to suggest a feature!
