Hi, I have a suggestion for new functionality, not found it if it is there sorry. It's about an option to add files, pdf, png,jpeg (can also , psd, psb, ai, etc formats) to the pdf itself while its inside. The idea was inspired by a competitor software which has a very easy oopia to add a file into an existing and open odf. Additionally in the wiggly ribbon are also arranged, add , move to another page, crop and rotate. I'm a student of ux/ui hopefully my idea really has the beginnings of adding usability fuctionality and most of all accessibility.
