<p>I think I've seen in some GNOME apps they use icon button with an icon like <code>view-list</code> or <code>view-more</code> or maybe some more semantically correct name for same icon. I guess the advantage of the icon is that it looks correct no matter which font or size being used (ex. in my browser here, it looks like an equal symbol).</p>
