When using Okular as previewer in PDFTex workflow, preparing beamer slides, the following usability hell occurred:
- LaTex/Beamer slides should be compiled to PDF with metadata "StartFullScreen"
- But while editing, on every PDF change/and reload, the user gets a modal popup "The document requested to be launched in presentation mode." "Do you want to allow it?"
- This makes typical Slide/LaTeX/Beamer editing workflow completely unusable.
- Completely disable this warning on reload of the changed document.
