Decided to make my own, here's how xat2's HTML5 iframe looks like - https://xat.com/xat2. It's not quite hard to do, but I can give some guidance on this if anyone needs.
I'd really like to see what other users create or get ideas from.
This is a functional one and there will be more functions apart from buttons to come and many other things to do once the quirks are worked out.
If you want to use it on your chat, here's the link: https://iframetesting2.s3.amazonaws.com/index.html // As you can see it has sounds and many other functions
