For the builtin icons, it would be nice if icons had multiple descriptors that are searched against, rather than just the name (and instead of listing them twice). For example, "X" or "remove" might show the "close"/"clear" icons. As it is now, it can be faster to scroll through all icons than to guess different names an icon may be under (particularly a problem because builtin doesn't contain all icons). Sometimes, it is so hard to find that it becomes easier to just go to iconify and copy one in.
