Ability to "remove" avatars

[TassSinclair]

Would be great to remove avatars without needing to refresh the page.

Something like a floating "X" near the top-right of avatars when hovered over.

Happy to propose a PR if it sounds like a good idea?

Thanks for the idea, Andrew. I'm planning to publish the source code soonish. Let me get back to you.
