I think you should be able to favoritize some things you may want to buy in the future from the points shop.
It could help with the indecisiveness of many people and people that can't or don't want to buy the things from the points shop immediatly.
Also, some people may write down what the want from the points shop but forget where they put it, or maybe deleted it from the notes app accidentally or other possible accidents.

I think that feature would just help a lot of people for numerous reasons.
