Sometimes I name and arrange my Publisher layers and sublayers (in sequence of use) so that I can make them visible one after the other, or even go back and review if necessary. This saves a lot of time rather than making PDFs or putting my work into Keynote, etc. But to do this I have to have the Layer panel open or in split screen.
Have you thought of having a small interface with shortcuts that would allow a presenter to go to full screen and then easily navigate up or down from layer to adjoining layer, with the option of going through sublayers under a top layer? This would be a fantastic addition since editing and presenting would be via Publisher.Thanks for considering it.
PS: You hyperlinking/anchor options appear to work for objects or PDFs but I see nothing layers.
