Review feedback

Now with unified style as agreed upon by Simon & Ian.

Rules:

- ID before all other props.
- All props before children.
- All props after ID in alphabetical order.
- Empty line between children.
- Semi-colons.

Note: I didn't touch the DiscoverUM3Action because that's it's whole own UI part.
