Catenis Flow functionality

I was watching the Catenis-Flow video at: https://blockchainofthings.com/catenis-flow I understand that is used the Node-Red pallet, what actual functionality does it provide on top of all of the Node-Red components?

Catenis flow exposes all of the functionality that is available through the Catenis Enterprise API Developer APIs. All of the robust power of the Catenis integration layer via the APIs (Application Programming Interface) is available through Catenis-Flow-Nodes that gets loaded into the Node-Red application. This allows you to build prototypes and production workflows communicating with to the Bitcoin blockchain, very quickly, minimizing the need to code while saving time and money.
