It would be helpful to have selectable text in the PDF output file so that students can copy/save text into their notes when reviewing the presentation. This would also help the students engage with any URLs included in the presentation.
As is, students have to type out the text manually or use a PDF OCR tool (which may not be able to accurately/effectively process a large multi-page PDF or distinguish text boxes from text included in any image).
This would provide a major accessibility boost for students during their revision.
