Hi there. We still have this open to look at. However, I wanted to let you know about something that I myself did not know until last week. In most browsers, the text box that you type in is draggable from the bottom right corner. You can actually grab hold there with your mouse and drag the box to be any size you like.
This may not work in all browsers, but if it works well for you that would be a simple way to make typing a response fit better with what you would like to see.
