[TYPO3] wfqbe: sorting results by clicking on column header

[Claudio Strizzolo]

Hi all,
I have a question about wfqbe extension.
Is there any way to enable the visitors to sort results according to 
different fields, just by clicking on columns headers?
For instance:

If not so, I guess this would be a nice feature to add sooner or later.
Greetings
