The form documenter module provides a table listing the field settings that a user sees when adding content. This is useful for doing audits of content types prior to a migration, or to provide a convenient listing for an administrator who wants to check the editing experience for consistency across content types.

There are both D7 and D8 versions of the module. The D7 version only works on nodes, but is reasonably stable. The D8 version works for all entity types, but is rather more of a work in progress. Please see the README.md.
