Instead of bookmarks it should be possible to create multiple layouts with different viewpoints and/or different layer visibility. There furthermore should be buttons to quickly switch between the different Layouts (like possible in Excel to switch between different sheets). And it should be possible to export the whole atlas in one step to either one File (eg pdf) or different files (eg. pdf, jpg...). It is important that it is possible to name the layouts and to use the name of the layouts in dynamic text. It should be possible to create a master layout.
This idea has been merged with Multiple Map Layouts in Desktop Layout View.
