I've noticed that there's only one "Website/Custom" link available to add to your profile. In my opinion, this is a bit frustrating for those who want to put links to several profiles on sites that don't have their own link in the "Links & Social Media" tab.
So my idea is that instead of having many links to specific sites and one custom link, it could be done in a similar way to YouTube.
If you don't know, what YouTube does is it allows you to add as many links as you want, with any URL that you wish in them instead of specifically, say, Twitter, Steam, and Discord.
If there's an issue with how many would be displayed in the corner of the banner, a limit on how many appear right there could work.
