The biggest feature that I am currently wishing for is the ability to organize my wish list into different subcategories.
Personally, I have “must have” items, “nice to have” items, “maybe” items, “thinking about it” items, “unlikely, but you never know” items – and I could go on… My problem now is that it can become quite cluttered. Also, I’m hesitant to send someone my wishlist because it has a lot of “maybe” or “thinking about it” items.
In the pre-premium days, I just had different accounts for each wish list, but that’s not feasible now.
My preferences would be to support different lists, just like in collections – in the Showcase view, your wish list would behave just like your collection where you would see your custom lists in the row below. In Management view, there would be a new column for lists and you could filter, etc.
Another complimentary idea would be to give a numerical score to items in your wish list (like a number out of 100) so you could sort the items and indicate their priority.
