Ability to view comments that were initially on a pdf document before uploading into Workfront. You are able to view the comments when uploading pdf as a document; however, when converting into a proof or using the pdf to create a proof initially, you do not get to see any of the comments (only the marks on the document itself)
To add this feature would be awesome to resolve since most of us deal with external partners that don't have any sort of management system to comment on assets and rely on Adobe Acrobat to include comments and edit changes
After all, Adobe now owns Workfront so it would be in their best interest to have their product work exclusively within any of their other systems :)
