This is the new topic to house all the feedback about the chat plugin.
Chat is still mainly available here on Meta for those in the @chat-testers group, but feel free to request access if you want to check it out. 
There is a chat channel attached to this topic to gather quick, ongoing feedback from people, and anything longer-lasting can be pulled out into its own bug report or feature request, etc (with a chat tag attached to tie it all together 
). If anyone is already comfortable with submitting bug and feature topics then feel free to skip reporting it in the Feedback channel, or you can use it alongside if you want to chat about the issue or explore it a little with others before writing it up. 
There is also an optional extra Focused Sidebar theme component available to work alongside chat which you can enable from the hamburger menu:
If this is the first time you’ve heard about our upcoming Chat feature you can check out the topic below for more details - and you can find all the other chat-related topics by clicking on the chat tag.
Happy Chatting!
