It seems that PDF Architect 6 can edit annotations, but not create them... Please tell me I'm wrong, and if I am, tell me how to add annotations.
Well, nevermind, I've just seen I need to pay for the Professional Plan. Now just please help me with ://forums.pdfforge.org/t/bookmarks-become-unfunctional-after-saving-file-from-acrobat-reader/13790
I am afraid I don't know the answer to this, best contact the PDF Architect support :
