Inventory management is really poor, everything that has something to do with retainer should get QoL update.

If you craft you need to :
1. right click -> search this item
2. summon your retainer
3. dang, you forget in which slot the items is so you right click -> search the item again.
4. right click at the 2nd ingredients, ohh its on the other retainer.
5. repeat no. 1-3

now the only way i can make it a little bit faster is by opening notepad and write down every ingredients. but i believe i shouldnt do that.
selling things is also a pain in the ass, but its a different story.
