This plugin does EXACTLY what I was wanting to do in terms of displaying PDF documents on my site, and I was willing to switch from the "classic" editor to Gutenberg because of it. Keep up the good work!

This plugin is currently the best way to embed PDFs into posts/ pages etc. It has a simple block which just works. The only thing I'd say is that it'd be nice if it also displayed the embedded PDFs in the edit view too (like this one does https://wordpress.org/plugins/embed-pdf-viewer/ but that one also has an issue, see https://wordpress.org/support/topic/uploading-from-within-block-doesnt-work/ ) (that issue now resolved so given that plugin 5 stars and downgraded this to 4 stars to reflect the fact Embed PDF viewer is not my favourite plugin for doing this) Actually, this plugin works a lot better on mobiles than Embed PDF viewer, and so this my favourite again so upped this back to 5 stars 🙂 I'd still like to see the PDF embed in edit view in this plugin too though.

Easy to use plugin as a block in Gutenberg. Showing the pdf-file with option to full screen view, download etc.
