hi,
I had a RFE for PDF Architect. Often is usefull to edit a PDF files with something like Inkscape 0.48 or LibreOffice 3.5, that perfectly render PDF files, expecially when are single page. Inkscape limit editing to a single page, LibreOffice sometimes break when the PDF is too much complex and with too much pages.
So as workaround, I split a multipage PDF in single page files using command line tools like PDFTK, edit the single page with better results, and then rejoin in a single file.
PDF Architect can be very useful if can split the file in files and then rejoin in a simple manner.
