Sometimes when answering a question or getting a reply for the question leads to multiple questions. And then there will be some kind of follow up questions in the form of comments and it quickly grows to a big chain. Also people have to either watch the top message notification icon or refresh the page to figure out that there is a change in the question.
How about adding a chat functionality to the Stack Overflow? Once the chat is completed and the questioner can mark the question/chat as answered and the chat can be saved as answer for future reference.
Is there any such functionality planned or how can I propose this idea to Stack Overflow?
