In each list there are columns. We can sort by columns. When we click the sort button, a "clear sort" button appears in the position where the sort button was and the sort button moves to the left. The default sorting is Ascendant so to get a Descendant sorting we have to double click on the sort button, so I think it would be nice if the "clear order" button appeared in the left position instead of moving the actual sort button and thus allow a quick double click.
