> How would you hydrate the app with data while you dev?
This is precisely what the scenes are for in the storyboard.js file - it allows you to create multiple scenes that render your components with different data / props.
(founder here) You totally can do this, we use it like that all the time. "Dev" edits the running application or component, not a scaffold - so if you've got {list.map(x => <Card>{x}</Card>} you can select each card and it'll map it back to the instance inside the map. Same with ternaries etc.
