profile banner preview

It would be really useful to see the profile banner when changing the pfp in the settings. When you have a pfp with multiple colors, you really want to get the right color. Right now you have to change your pfp and hope for the color you want. For my pfp rn, I want a blue background but I also want the burger part to be as big as possible. I can't know (in my 2nd picture) whether I get a blue or a yellow background. I'd have to click the button, hope it's good. But if it's yellow, I'd have to wait a few minutes (idk how long) until I can change it again.

This can also be solved by giving non-nitro users the possibility to change the background color without changing their pfp.
