Custom paper size
Submitted by OCLC
It would be great if the paper size could be customized at will, instead of being limited to the values in the list.
For example, I organize a UML diagram so that it spans a few pages on the Dia window, for future export to PDF and include in a Latex document. Because the paper size can not be customized, the aspect ratio is wrong. [OK, I can crop the PDF afterward with other software, but it's dirty work]
