Not show the PDF icon but preview of content
When you have several PDFs in the media library, they all look the same in the playlist and available files in the library.
I like that I can easily identify that the current item is a PDF, but as with videos, I'd like a preview of the first page or similar. As of now there's a lot of mouse hovering to identify what PDF is what.
I suggest a small PDF icon in the bottom right, and a preview of what the PDF contains.
This feature has already been implemented. We will provide this in an upcoming release.
