BePDF Versions 0.9.3, and later, now feature, by popular request, Tracker attributes!
Open a Tracker window containing one or more PDF files (the window can contain other types of files, also).
Change the Tracker window contents display to 'List View'
Select 'Attributes' from the Tracker Menu
Select PDF and choose from the list the attributes to be displayed
Exit BePDF, if it is currently running
Start the FileTypes BeOS Preferences application
Select and remove the filetypes application/pdf and application/x-pdf
Restart Tracker
Navigate to a pdf file and double click it
In the dialog box that appears, select "Find"
Select BePDF in the "Open With" dialog box and choose "Make Preferred"
Now in any Tracker window with a pdf file, under the attributes window you will find a listing of valid pdf attributes to display
Simply use QuickRes [http://www.bebits.com/app/1504] or another similar BeOS attribute editor to change the PDF file Attributes. These changes will be saved with the PDF. BePDF will not overwrite the edited attributes unless the command key is pressed while the file is being loaded--the file attributes will revert to the default BePDF attributes at that time.
