I find the implementation of widgets in the Sidebar Instant App to be to be a superior way to display any tool widget rather than the traditional window on top of the map that usually needs to be moved, resized and does not show enough information. This is why the Tab Theme is my favorite Web AppBuilder Template. In Experience Builder I use the sidebar widget, add the section widget in the left sidebar window, and load all of my action widgets into views within the section, including the Feature Info widget. I then link a button to each view to open the widgets, rather than the views navigation widget because I can make the buttons look nicer. The functionality if very much like the Sidebar instant app and the Web AppBuilder Tab Theme, and is very intuitive. What I have developed took many hours and is a bit of a hack. I think it would be very useful and more time efficient to many people to add the Web AppBuilder Tab Theme as one of the WebAppBuilder Classic starting templates.
