Implement a channel on the right side

On the far right side of the editor, please add a chat box.
I was just making a project with my friend, and we took up 20 lines just chatting about how to do something, an in-editor chat embedded on the right would be very useful to prevent flooding code with comments

i have a sulution of just making a file called chat/.txt (yes exactly like that even the /) and you can then use that

Then we have to switch that file to see the messages, the point is to have a window on the side that is always visiable to make chatting easier.
