We're working on bringing this back :)

I've said this in a few other places, but essentially wishlist search will be added back after we do some pretty major tweaking to wishlists, because if I'm honest they're almost as bad as the old shops. We don't have a specific timeline for it at the moment, but hopefully within the next few weeks. :)

doubtful.

they're not really because they're not constantly being used and changed like shops are.
