FEATURE: Improve UX of generate entities form in investigations -> wizard? #3066
Description
Is your feature request related to a problem? Please describe.
The UI/UX of generating entities is confusing for many journalists, preventing them from using it without assistance. Specifically, the concept of keys and uniqueness, but not only. The concept of creating relationships is confusing because the current UI treats relationships as a separate object, but that is not how journalists thing about relationships. In addition, journalists often consider the mapping of columns to properties and choosing keys to be the same activity, even though they are distinct steps in the process of generating entities.
Describe the solution you'd like
A better workflow for this process that is self-explanatory, walks the user through the process, and makes each step very clear and attempts to choose sane defaults automatically when possible. Sane templates for common mappings.
Describe alternatives you've considered
Let the data desk do it for me.
