I think you should be able to open cosmetic keys in bundles or at least faster than the way you have it now. It takes me forever to open a lot right now because they take a few seconds each. Its very annoying especially since i just want a few things and there are hundreds of possible rewards. I also think it would be cool to be able to buy cosmetic keys with credits, after you have bought every power-up in the minigames your credits build up a lot and we could use those credits to get keys, there are so many hats that i am missing and i would like to be able to get them all.
