Add a wishlist to the store#129

Let us keep track of the items we want without having to surf through all the clutter. We should also be able to buy items through said wishlist.

Great idea, but sadly not on our roadmap right now. We have other features planned for 2026 that our engineers are focusing on (items, workshop, etc.). It’s possible something like this could get added in a later phase of some menu updates we have planned.
