[Feature Request] Personalization overhaul

[NekoBelmont]

RA by itself is a great concept, but I think the lack of major customization can harm user's experience and thorn some people away.
I thought on some ideas that not only me, but I'm sure a lot of users would like to see as well.

Let the user change the color scheme for backgrounds and texts

If one could have a bigger piece of itself on their profile, they would be more optimistic on getting cheevos, and I think this is a great way of doing this. Even having a simple background gradient would be nice, Linktree does something similar.

Select a specific mastery to be on focus

I think everyone has that specific badge they're proud for. Let them select it to be on focus, bigger, alongside your profile.
It's one more personalization layer I think everybody would love to see.

Custom banner

Nothing really heavy, a small image/limited gif with a preset size would fit perfectly to clean the darker gap on user's border.

Balance

To avoid server overload, make sure that only users that reached a certain number of points are able to use custom banners, it would serve as an incentive to master games as well.
