The comment length here is such that it corresponds to what normally is a long paragraph in usual written communications.
In some situations, it is more natural to write two short paragraphs, or one bigger paragraph followed by a short conclusion on another line.
Implementing this would be very helpful. So far, to achieve this effect, I had resorted to inserting a blank MathJaX line inside the comment. It works, but the spacing created is way too big.
Please end this continuing bother and misery and allow newlines inside comments. It would allow much better formatted comments in certain situation.
People keep hitting enter key while typing comments, and the reason is that it is very natural sometimes to break a long comment into two paragraphs. Not only that the "comment" box works like an HTML textarea, but also it is true that it is natural to insert multiple paragraphs in this textarea.
So please try to incorporate this feature. This would also alleviate a lot of ongoing friction, and gratuitous humiliation meted out to particular users on this account.
If there are others feeling the same way, please try to post other similar feature-requests. Perhaps the higher-ups might change the mind when there is enough demand. This or that particular request might get ignored in the past; but it is worthwhile if it is done in the end.
