Video players like IINA let you view video in a floating, borderless window.
Is there any equivalent for PDF files?
I'm using PDF slides and am basically trying to get the equivalent functionality of viewing a PDF in full-screen (no window decorum, left/right arrows to move through slides), but outside of full-screen.
Alternatively, any software that can display PDF in some approaching way would be very welcome. Perhaps something like what Simple Comic does (automatic window resizing to the content)?
