Formatting of Gantt Chart for PDF export

Hi all,
There really needs to be some improvements to the presentation of exported PDF Gantt Charts. An exported format is the way that most people on a project (other than the PM directly) will consume this data. The current PDF export options are lacking a lot of control.
- I'd like to firstly have control over the export size of the PDFs (A4, A3 etc), Currently it seems arbitrary - very large aspect ratio print sizes.
- Next i'd like to be able to specify the print date range, and scale (show days, weeks or months) - then automatically break the pages to maintain the presentation. - i.e. printing several weeks, with a scale showing days in detail would allow a task to spill onto multiple pages horizontally, but a long list of tasks would spill onto pages vertically.
- Text scale, and date range scale should be controlled independently, so I can make sure text is still readable even as I reduce the date range.
- I should be able to include/exclude a legend on the printed page.

I'm looking forward to being able to share my project timelines with users in a more readable manner.

Thanks
