wiki page to .odt

[atdqm]

Hello,
Would it be possible to have a module so a wiki page could be exported as an .odt file? Right now the only way to do this is to print the wiki page as a PDF and then convert the PDF to .odt. This is cumbersome. I think it would make the wiki more user friendly if there was a module that could do this. In terms of work flow and backing documents up a print wiki page as .odt would save time and improve HumHub.
