I would like to export pdfs to Adobe and Dropbox as well.
You can export PDFs to any app that will accept a PDF.
Yes, just choose the "Save to device" option when exporting.
Is it possible to just export (or print) a PDF file from Squid the conventional way (ie. just create a .pdf file on disk without involving another app)?
Apologies for my tech ignorance - I'm new to the concept of 'sharing' between apps.
