I am currently using PDF Creator to create PDF files, and just installed Nitro PDF Professional. I am surprised that there is no way to tell the print driver to collect my output and eventually merge the pieces into a single file. PDF Creator allows this, in fact they have a very nice user interface that allows you to reorder files in the queue and then merge pieces of them. I don't think that Acrobat does this either, but considering that PDF Creator is a free product, I am surprised that they have it and a pay product does not.

Between this and the lack of thumbnails in Windows Explorer, I will have to keep using both Acrobat Reader and PDF Creator on my machine and only use Nitro PDF for editing.
