Your proposed print feature is a very good idea. I would like to have the option of going directly to the printer. I would like to have the option of a preview of what was going to go the the printer.
Another important inclusion, besides just the text, is the inclusion of the voice card heading and subject. Both of these are worth the extra space. You might have their inclusion as an option to printing the voice cards.
Or am I asking for the moon?
[Editor's note: I don't think I can manage the preview feature, but other than that you wish will (eventually) be granted]
