Currently, when you add a link to your profile, if it is one of a small subset of websites, it gets an icon that matches the iconography for that website. Examples of these off the top of my head include Github, Twitter, Gumroad, Twitch, etc.

While this covers most cases that people use the profile links box for, people who want to link personal websites (portfolios, blogs, personalized link redirects, etc), or websites outside of that small subset are doomed to forever exist as a generic link icon that tells nothing about what it is on first glance.

My suggestion, is that VRC+ users be able to set the icon that appears for each link to a specific "User Icon" from their gallery. This would allow VRC+ users to create icons that fit the website they are linking.
