In the Classic Cascade Story Maps there were an option to select different transition options between pages (see also attached screenshot):
- Fade
- Fade Slow
- Swipe Vertical
- Swipe Horizontal
- None

These gave some very impressive options to reveal differences between images, photos and maps. In the new current ArcGIS Story Maps there are only the following options (see also attached screenshot):

It would be very much appreciated if the same options were available from the classic Story Maps.
