I was reviewing a pdf paper using okular. I would choose save-as to save the document in which I highlighted text, but I did not do that recently.
I was also multi-tasking between other things I'm doing or that require my attention. Later I realized that somehow, the okular session in which I was annotating (reviewing) the pdf paper had been inadvertently closed and I've lost my annotations for the last half day.
Is there any auto-save feature in okular that can enable me to recover the lost annotations instead of having to redo them?
