It would be great to have in WAB the ability to switch between multiple applications by clicking on some tabs.
When in any of the applications you zoom to a particular areas, the other apps should automatically pic the same map extent.
The apps should be able to use different webmaps and widgets.
This would give the ability to create a single go-to place for users that have the necessity to access webapps that are similar but focus on different thematics without having to access these apps one by one on AGOL/Portal and or having to log in each time.
What do you think?
