Please add, ability to change the sort order of the transfer list

[shodanx2]

The transfer list has columns, but clicking them does nothing.

Clicking them should re-sort the transfer list via that column.

Clicking the same column should re-sort the transfer list in the inverse order

For similar behaviour, see Voidtools Everything

The transfer list can already be rearranged, just not sorted

Hi,
This is algorithmic problem: on large list the ultracopier was click on this, and all freeze because the sorting logic si too heavy in CPU.
