PDF Auto-save [Feature Request]

[microbearsmb]

Thank you so much for this awesome open source scanning app! It has served me well. I have a few requests to improve it - first, could there be a setting to enable having all scans automatically saved to PDF at the default save location (updated whenever a page is added)? I always save my scans as PDFs, and so there a several extra clicks needed with every scan. It'd be great if that happened in the background!
