This has been bothering me for a while now. When you are in a chat-room for example in Stack Overflow, you are also able to be in, at the same time, as many other rooms in the Stack Overflow chat.
The same goes for Meta Stack Overflow, Super User, etcetera.
The problem is that for each different Stack Exchange site you need to be in a different tab (or window depending on your browser) for each Stack Exchange chat area, and you are able to be in many chat-rooms in those windows (depending on your reputation points).
What I am requesting (suggesting) is for a Stack Exchange chat-room area where you have all of the rooms that you are in on the Exchange in one place and are able to get all of the responses and replies in one place without the need to change windows as you do now.
