How do you make the comment area smaller? Whether or not avatars are enabled, it takes up more room than I would like. One of two sentences take up too much space. How and where in the theme may it be adjusted?
Since the comment blocks are already separated by space, how about removing some open space inside the box? The top empty space (line) and the bottom empty space, for instance. Have the comment text start right after the line for the box and then end along the very bottom.
