We can sort hats and show unlocked hats, that's really cool.
BUT, It would be great to have a preview of the hat when is not unlocked yet (or if u have x0)
Like in the hats menu we could click it, showing it up on our player but it is only visual, it will not be applied because we don't really have it.
Maybe beware of gliches like the player closing his game while displaying the hat preview and then he brains the system and have the hat even he didn't unlocked it. (maybe it won't happen, just a thought)
