It would be nice to have a widget that allows you to predefine multiple layer visibility configurations. Perhaps by adding an option to the Bookmark widget not to save the location or by adding more options to the Map Layers widget. When you click on a bookmark, the visibility of the layers should change, but the current extent should not change. The current Map Layers widget is not what I'm looking for as you have to disable and enable each of the layers individually. My current workaround is to have multiple connected Map widgets and toggle between them using links in buttons. But it's not nice because it has to reload the view every time you switch between maps.
