Let us spend Pack Points when browsing our collection

The most obvious place to put the Pack Point Exchange button would be when browsing your own collection, the My Cards area. Here, in yet another unlabeled feature, you can toggle an anonymous switch at the top to reveal the gaps for all the non-secret rare cards in your collection. Tap on these, and you can see all the details, except for the artwork (and indeed wishlist them).
But what you cannot do is buy them with the Pack Points! It’s such an unbelievably obvious option, making it downright odd that it wasn’t in the game at launch. Come on, Pocket, do the right thing.
