Add View: iterate data source initial step interface

[karmatosed]

Is your feature request related to a problem? Please describe. The current interface for the data source could be iterated on to improve usability. The goal wouldn't be to at this point change it as much as iterate with the existing interface elements. The current one is a little confusing to work out what each means and how to follow.

Describe the solution you'd like By adopting a simpler format using rows this would be easier to view. There is also some copy change to make it clearer. This likely needs some work though.

Describe alternatives you've considered If there was no view title the following could also be considered which brings in steps.

There is more could be done here with a different interface, but as noted the goal was to use the existing format and just iterate within that.
