'Export to PDF' should remember settings

Use case or problem

When exporting to PDF, the settings reset everytime the menu is opened. This is especially annoying if you just need to change one thing in the document, or want several documents the same. Personally, I have to change Letter to A4 and downscale (can this have a input box?)

Proposed solution

The dialog box should remember settings by default at least, possibly as an option. Being able to set presets would be nice too.


Will add in 0.10.9.
