And more to that answer....
You say you want a list without the arrow. I have suggested a way or 'removing' the arrow. I think the use of the gif is hardcoded for now, but is expected to be removed in version 4.1.0 through templating. I think the titles should form a list, unless the titles are too long. Then, you have options, do you let them wrap, or make the box wider, or add scroll bars. These can all be decided via the theme file. I'm no expert on Theme css files, but I'm sure you would get some guidance here.
