I like how RIF (Reddit Is Fun) does it. If you click on a comment (or post on your front page), it reformats the comment box so that it opens up additional options. One of them happens to be collapse among other basic commands like reply, report, next parent comment, previous parent comment and stuff like that. It makes the comment and front page sections a little bit more compact and easy to read quickly without options cluttering the interface. The voting options are the only options that stick out without clicking on a comment so you can easily upvote/downvote and move on.
