Problem/Motivation
On the first iteration of the prototype from https://www.drupal.org/project/drupal/issues/3343940, we noticed that the way that we chose to represent the available field types was overwhelming. One of the ideas we had was to try to come up with a better grouping of the field types, to hide some of the complexity.
Proposed resolution
Group fields together to make it less overwhelming based on the findings from https://www.drupal.org/project/drupal/issues/3346539#comment-14999770
Remaining tasks
User interface changes
Fields
"Subfields"
