View/ link to attached files when pdf is open

I’d enjoy having a more convenient way to access supplemental files while reading the article. I’ve attached the files to the article, but to view them, I have to go back to Paperpile and navigate to the article in my library, etc (I might not have the article already selected).

For files that can be rendered as some sort of text, it might be nice to just append them to the bottom of the pdf (if I keep scrolling down, I’ll get to the supplement). That way I don’t have to worry about merging pdf’s or anything. In this scenario, some sort of navigation tool will still be nice (click ‘here’ for main article, ‘here’ for supplement1.pdf, ‘here’ for supplement2.txt, etc).
