I think it might be better if there will be a chat settings and we can change the size of chat box. It's true that we can hide chat box if we have any problem with it, but if we hide this we can't even talk or see other's messages. And sometimes for this, chat becomes dead, which is boring. So, my suggestion is-
Make a settings where we can change the chat size. Example: 1x1 will be the normal size of chat box, and if we make the size 1x0.5 then the hiegth of the chat box will be normal but the width of chat box will be half. But its wull be too short to make chat box half. So you can add 2, 1.9, 1.8, ............. 1, 0.9, 0.8, 0.7, 0.6, 0.5. And we can change both of height and width separately. I hope, after this the chat will not be dead.
