1st Suggestion:
You shouldn't be able to quote a comment and then edit what they said. I've seen people do hurtful things with this.
I disagree. The people who abuse this feature are the minority (at least in my experience) - I have rarely seen it. Thus, I don't think this feature should be removed because a few abuse it. Rather, I think the majority should report those who misuse it. After all, it can be quite helpful especially when you only address a portion of a comment (this comes in handy with especially large comments), such as I am doing now.

2nd Suggestion:
You should be able to click on a quote and have it send you to the original message. It would make searching for comments much more convenient.
