Hi, the site doesn't have a wishlist feature, do you mean that we should rename "shelf" to "wishlist"? If this is the case, I am not quite sure if this would be a good idea. It puts too much of a "commerce" tone and tint to the term IMO.

I kinda like the 'add to my shelf' because it is like your digital shelf. The lists are the ways that you can differentiate and organize. The shelf is just the one big library that has everything. My $0.02 on it anyway.
