This menu offers some useful switches for layers:
FOR THE VIEWPORT:
- layer activation
- layer visibility
- layer combinations
FOR THE PAGES:
- visibility of a layer in all pages
- creation of new, exclusive layer or text-layer for an active page.
(an exclusive text-layer can be very useful for page-specific descriptions)
Creating exclusive layer makes the workflow for presentations much easier.
If you have an exclusive information for a selected page, which shall not be visible in other pages, create a exclusive layer for this.
This layer then is invisible in all other pages (unlike adding a new layer in the standard layer menu or simply adding an invisible layer, which is not automatically included in the active page).
