Firstly, I must congratulate the administrators and all of the people contributing to the updates that we are seeing. I understand that it's not easy to build these things. Switching to HTML5 shows a commitment that is necessary to maintaining this website, so it's easy to see that this website is not being abandoned.
This post is a response to @SLOom. I have decided to post in this topic since it is relevant to this topic, and to avoid making the other topic go off-topic.
When most people communicate, they are not speaking in literal terms. I did not mean, nor would it be reasonable to assume, that the redesign is exactly the same as the old design. Of course it's not. But how is a dropdown menu surprising? Am I supposed to say thanks for a dropdown menu that we should have had nearly a decade ago?
It doesn't matter if it's in beta or if more features will be added. The general design of the chat box and its related features still hold the general design of 12 years ago.
I did not mean that we should have used Bootstrap 4 specifically years ago. Why would you assume that I meant that? That doesn't make sense.

Additionally, you said this to Arthur: "It will never become harder to browse flash chat. Chrome is smart enough to add settings in their browser to still allow flash as well."
Please take a look at The Chromium Projects' Flash Roadmap:
Flash Disabled by Default (Target: Chrome 76+ - July 2019).
Flash Support Removed from Chromium (Target: Chrome 87+ - Dec 2020).
