How does the "Set view definition" command work?

There is a command called Set view definition. It can set the Group, Sort and Display settings of a node view.

There is no good UX for this at the moment, so the instructions are not conventional nor friendly for beginners. But right now, this is one way of doing it:

• Mock up a node that will have sample child nodes representing the data you'll be applying this command on
• Then, create the exact view settings you want with Group, Sort and Display.
• Go Cmd/Ctrl+K > Debug Node on the parent node and look at Views for node:

• Clone the fields over to the command node so it looks like this:

When you run this command on a node, this should change the view settings according to your configuration.
