Please make the message window bigger when replying to tickets.

4.5 rows is waaaaaay too small to get an overview of one's reply. And if you're typing out a longer reply and want to proof-read it before sending, that is way more annoying than it has to be since you have to scroll up and down so much. In the attached screenshot I have only generated lorem ipsum with 3 paragraphs and this is what it looks like.

Either simply make it bigger or make it resizable, either would work just as well.
