SEVERAL people ask me for my hack codes of dokuwiki that I used in
http://alu.dc.ufc.br/wiki and
http://alu.dc.ufc.br/~silveira/kuruwiki .
All that I did was changed some little pieces of the inc/html.php .
So, I'm think its easy to add this feature.
obs: I would like to do that but I haven't that level of php experience.
