OK but it's confusing for authors @ least: in regular Story Map it shows on Settings then on app itself (per my screenshot), whereas in Cascade SM it shows on Share dialog box (per ur screenshot)... Might you consider normalising to one or the other?
And thx for the kudos, I went to SM landing page to submit it but found that page missing, so I tweeted you instead LOL loved the ability to add web scenes tho mine isn't the best, & y'all get top marks for ease-of-use! @owengeo @allencarroll
