Explain the problem as you see it
We can currently read a PDF within Tana but even when expanded to a full node there is a large area of screen real estate that cannot be used by the PDF text and I find it a better experience to open PDFs in a different application.
Why is this a problem for you?
When viewing PDFs I find it useful to utilize the entire screen and it would be great to be able to do this all within Tana and not have to open the PDF with another application.
Suggest a solution
At least have the ability to view PDF files as full screen within Tana. Logseq has other great PDF features which would be great in Tana but even just being able to view the file full screen would be great.
