Currently, if a pdf is uploaded, it doesn't have a preview as shown in the attached image. In the attached image is also a random png, which does have a preview, and this is the behaviour i'm requesting. When working with lots of PDFs, a built-in viewing system is essential, because otherwise the pdf has to be downloaded first to open in a different application, breaking workflow. Although on desktop, using the taskade web app, the pdf is displayed in a new tab, but on mobile this is not the case. I saw a different feature request also asking for annotations (for pdf and images) which I have upvoted already, but this feature request is just about the previews. If this would have been better as a comment, then this can be merged or deleted.
