Create a button that temporarily sets some configurations: full screen, no effect for page transitions, black xodo background, no continuous scroll, and anything desirable for a PDF presentation.
It would be even better if you could draw with laser (and the drawing fades) like it happens in goodnote

It would be better if xodo has function of pointer, just like the laserpen/pointer in ppt. This will make the online class easier.
Presentation pointer would be great ... specially now for online lectures. Like in e.g. drawboard
It would also be nice to have some kind of presentation pointer: Instead of directly writing into the PDF, you could show just a trace of the pen (like a laserpointer)
