I've been looking into the Dashboard theme in WAB / WAB DE and it would be nice to iFrame content from other websites into some of the panels.
For my specific purpose I was using this template for election results. The map and left side of the theme was used for my County's results. It would be nice to be able to iFrame the results from the State and even Nationally right within the Application.
Similarly, this could be used as a Common Operating Picture for emergency response. The frames in the themes could contain data from external or internal websites as a means to give a manager more information in one location.
