As far as I can tell, right now KPVbooklet only adds entries to the homescreen that would otherwise not be there because the default reader doesn't support them.

Is there a way to make it so that KPVBooklet also opens PDF files? I've found that Koreader renders them at a higher quality than the default reader.

If this causes pdf files to be displayed twice (one for the default reader, one for Koreader) that's fine as well.
