EDITING PDFS EVEN IN LIQUID MODE

As a student, I have to read many PDFs in research papers articles notes in which the liquid mode has been a grate help. But the only thing that bugs me that I have to exit the liquid mode to highlight or mark the points.

It would be a grate user experience if I won't have to exit the liquid mode and was able to highlight within it and still be able to reflect the edits. It would make the students really happy trust me.

Thanks.
