Is your feature request related to a problem? Please describe.

I would like to expand an arbitrary list of the external links I can provide.

Describe the solution you'd like

As a blog author, I would like to add custom links to my social media profiles, individual projects, and also sites that allow donations such as BuyMeACoffee, Patreon, Paypal.me etc. So that I can direct people to the content that is not fit for a blog or sites that allow people to make direct contributions

As a blog author. I would like for custom link icon to be auto-populated from favicon of the referenced website, So that I can retain the current template and have clickable icons for each external link

As a blog author, I would like to edit the custom link icon So that I can maintain icon/theme consistency throughout the team in case the default logo is clashing with the design

Describe alternatives you've considered

I've also considered adding those links to the custom About page. The concern is that these links are not visible on every page.
