In a different question, I was given step instructions for converting my old version of Shortlist to the new Beta. I tried it, but I do not see the option that I need. After Share > Create a Web App, I am not given the option to build a story map, it just has the list of old and retired web app templates.
Also, some suggestions that would be really appreciated in the next/future updates:
1) The ability to change header colors and upload a banner. Also to change colors in the Tile List
2) The ability to add a search widget
3) Import images from URL
4) Add/change basemap
