Several customers (educational and local government) suggested they would like to have a 'Convert to PDF' option on document. This way the document can be converted to a PDF and be annotated with another solution (planning for Filr 2.1?) or shared as a PDF.
There is also an advantage for this versus the HTML preview option, cause a PDF has the page numbers in the document while a HTML preview using the document converters shows a readable preview of the document without pages (or page numbers).
Technically the PDF conversions service should run on the Filr Appliance. I think the PDF's should be saved in the VA shared area. Once a document has a PDF equivalent it would be nice if it gets updated automatically case the parent document is updated.
