Note that rEFIt does not wrap the icons, it scrolls them if there are
too many. And there is good reason for that, navigating a table is
quite tedious, and when a new item is added in the middle the table
shifts in ways which make it hard to find previously existing items.

It does, however, have tow separate strips of icons. One strip are
tool icons, the larger one are the automatically gathered OS icons.
