@
kaufman - maybe you could add books to be auto converted using the the auto add facility, see
Preferences->Add->Automatic Adding tab. It has a separate check box for auto convert. And add the PDF's and CBR's manually with the auto convert off. Or vice versa - auto add the PDF/CBR's with no auto convert and manually add the rest with auto convert
Or maybe you can get the Quick Preferences PI enhanced to include Auto Convert as a setting - see
[GUI Plugin] Quick Preferences
