Set sort direction instantly in context menu in column header.

I would like to have a small right click context menu on each column header in the list view, which should contain the items "ascending" and "descending" (or their abbreviations) to set instantly the direction of sorting.

The state now is:
User wants a descending sorted list.
User has to click on column header.
Then Mp3tag does the sorting in ascending order.
After this prodess has finished, the user has to click again onto the column in oder to get an descending sorted list.

It is always annoying to wait a few minutes for the result in case of a descending sorted list.
It would be helpful to have the "ascending" and " descending" order directly in the column's header context menu.



This would be very useful
