I would like to see a solution in Story Map Journal App Templates (Specifically the Tabbed Series) that allows the creator to add a splash screen. Between the Tabbed Series and Side Panel Journal Map I use those applications regularly for executive briefings (Replaced PowerPoint). I would like to add some sort of language/verbiage to the application that gives it that authoritative support. Something similar to what you see currently in Web App Builder would be the solution that I would be interested in.
I know I can download the source code and host it on my web server but that would be my absolute last option if I can't find a quick fix.
