This is a great and very useful project.

I don't have the skills to add new features but if you're looking to add one, I'd really love a "Save to CMIS..." feature. CMIS is a standard for document management systems and there's already a Perl module for it: WebService::Cmis.

Requirements would be to:

  1. Add a file menu item "Save to CMIS..." allowing navigation to a CMIS folder.
  2. In "Save to CMIS..." dialog, a button to select (and set as default) the CMIS repository (URL, username, password). This can be stored permanently.
  3. The password can be entered only when needed.
  4. In "Save to CMIS..." dialog, an option to select a directory/folder and retain list of preferred CMIS folders.

Sample use case:
Feed stack of paper in scanner
Launch scan2pdf
select scan button (window appears with default scanner selected)
select profile
press scan (pages scan)
press close
Select File>Save to CMIS...
Save to dialog appears
press icon/button "Select repository"
dialog appears
fill-in URL, user name, optionally password
press OK
connection takes place, root folder is displayed with sub-folders
select sub-folder after navigating to the correct one
enter document name
press save
dialog to enter password appears
enter password
press ok
document is saved in PDF format in folder requested

Thanks for considering...
