Experience builder version
1) select layer window and legend window can not present at same time.
2) select layer window and legend window hard to find, have to click one of button on map top. Once opened, it block map view, also window is too small hard to scroll down.
Native arcgis javascript api version
1) select layer window and legend window are always visible to user at same time without any button click to open.
2) select layer window and legend window do not block map view, when user change layer selection, user can watch map change and legend change in real time. Not like experience version, blocked map view, have to switch between layer window and legend window.
