re-organizing cucumber features
show opt-in prompt after log-in, but only once (not every time)
NOT PASSING -- PLACEHOLDER COMMIT -- hijack features in place and failing... time to implement
STILL NOT PASSING -- however, y4y. hijack main app controller to add helper and before_filter
NOT PASSING -- don't include gringotts_next_url flash message in notifications
protego! hijacks and redirects for first-time users to see prompt
note: issue with devise flash message logging in; 'pending' for now =/
Gringotts::Vault confirmed_at after confirming phone number
verification sticks around in session; user can bail out before confirming
TODO: wip'd sign in message and device-recognition...
first-time users are never locked out while trying to confirm phone number
cucumber @wips for opting-out and changing phone number
