I have one:
Is it possible to add custom social media buttons (instead of you adding them one by one as needed)? Perhaps similar to adding links except that you also provide the ability to upload the button image (svg or png).

I ask this because the social buttons I need are rather niche: Quora (profile), StackOverflow (profile), GitHub (profile). And if you'll notice these are not APIs (as needed for actions like follow) but rather just URLs. But they still merit using social media buttons since they are platforms w/ social (community) component.
