Whenever, I try to post a comment, etc, I have to type in those weird text boxes whereas I clearly need a textarea to type in because it's a lot more suitable. I think a textarea which automatically expands as we type just like the one in G+ would be amazing. Moreover, I think Bucky should consider preserving all the lines we create while we type. We don't want to create a nice little comment with proper paragraphs and stuff and later find it cramped into a single lines, messed up already.
