I wish you would change the way how clicking on column headers affects the
sort order of the tickets in the search window:
now: with every click to any column the sort order (asc, desc) allways
toggles, this is very unexpected if you only intend to change the sort
category by clicking on a different column.
more useful would be: click to a column only changes sort category, click
to a separate link changes sort order (asc, desc).
