I have a channel with an Assets field, designed to hold PDF files. It works fine to select one or more files, and/or upload files and select them. However, I'm wondering if there is a way to view a PDF once selected, from the add/edit entry screen.
I'm guessing you may have found an answer to this, but have you seen the download assets plugin? It puts a download button next to every asset on an edit page that links to the asset's url.
