Custom columns & Search list box – no extension shown

The column headers are always there so you can SORT by name and extesion. This is intentional and will not be changed.

I see they are there intentionally but for no reason. As said before there are their optional counterparts available to append to column set with expected functionality.

Nonetheless faulty or at least weird behavior noted in point 1 and 2 is still present.
