Web AppBuilder for ArcGIS-Portal currently has a Bookmark widget where you can save locations on your map.
What would be nice is if there was a Bookmark widget for layers shown (turned off/on) in a map.
We have built maps which contain 150+ layers. These are used by agencies with hundreds of employees in multiple teams.
We have received feedback asking if layer bookmarks can be setup for each team. i.e. team A needs layers a,b and c. Team B needs layers x,y,z etc.
Unfortunately we can only use the standard version 10.3 of Web AppBuilder and not the Developer edition.
