Now that Scenes are released and I see the UI I now understand why they did them separately. As you suggest, AdamV, I had originally posted a concept that added a Scenes feature directly to Routines (Suggestion For Scenes within Routines). However, this would only allow Scenes to be triggered from Routines. With them separate, a Scene can be triggered in other ways.
Like Tgauchat suggested, I too would like to be able to capture the current state as a Scene. And the lighting board idea is such a good one. I’d especially like to see how that feature could work in ActionTiles…
