Comment window is not enough. Can I do something with him?

Dear Hubris, please tell me if something can be done with the form for adding comments. The fact is that here , for example, a rather long comment line came out. Plus people write rather big texts.

I don’t know how to others, but subject to the use of citation tags, and even large response texts, it became extremely uncomfortable somewhere in the middle of a discussion.

But maybe I just do not know the obvious solution, which has long existed? And if not, then you can enter the same in size (obviously rather big) forms of adding comments? Horror as uncomfortable.

Otherwise, I'm afraid, after a few replies, the comment window will be the size of a matchbox. :)
