Feedback: the format for stickers

On some other sites I enjoy stickers, but I think there's problems with Discord's initial implementation:

-"shopping" in the tiny pop-out window is causing my computer to struggle

-I'd rather shop in a new window with a store-like feel

-I have no control over my collection except being able to add to it (can't delete or sort?)

-instead of "frequently used" category, I'd prefer a "favorites" list where I can flag my own choices of stickers that I like best (and I should be in control of how many favorites I want, ie. if I want only 1 or 2 favorites, or none)

-they're just plain Large. Too big.
