When creating StoryMaps through ArcGIS Online - there used to be an option where you could click on the Design tab and there was a link to create your own theme. I noticed that it's been gone recently and thought my brain had made it up - but I've had a few users ask me about it that had worked on StoryMaps in the past.
When creating StoryMaps in ArcGIS Online (because we don't go through storymaps.arcgis.com), to have a link that will allow you to create your own custom theme, instead of having to go to the separate StoryMaps site. You can browse themes that you've made, but there isn't a button that allows you to create a new one.
Thank you!
