I would love to see some options in the way the web app is displayed if you have it embedded into another website. I regularly embed web apps in a StoryMap Series, and I do not need a title bar etc. when I do that. I often use the Tab theme in WAB, but also in other themes there is always a title bar on top.
I think there could me multiple ways to do this;
- implementation of URL parameters, just like the &embed option with StoryMaps
- option in the WAB where you can choose yourself if you want the title bar or not
- some way to do it in the ArcGIS Online Assistant by editing the JSON
