Placement of chats windows throughout the application

I think everyone has ever wanted to communicate in several chats at the same time, and I think that the function of separating the chat from the application will help with this. This function is used by the application in threads. When a window with a thread appears on the side of the chat, and a person can correspond in both chat windows at the same time, without overloading the computer when switching from server to server, when they discuss tomorrow's walk on one server, and in the other they discuss an event in the game.
