New themes

I wanted to ask something. It might be a bit much to ask but maybe it can be cool.
Can new theme's be added to discord? Then I mean like basic theme's for non nitro users and animated or special ones for the nitro users.
I think this can make people want to buy nitro even more to be honest and it's cool to have something different for once. I'm already pleased someone read this and maybe I'll see something soon! (or not)
