Summary
Field UI Plus adds a modest amount of data to the administration configuration
page provided by the Field UI module. This helps to see the important field
instance configuration settings at a glance, without having to walk through
numerous subpages.
Cautions
This is intended for use with the default Drupal 7 administrative theme, and
will no doubt look terrible if used in other administrative themes.
Rationale
The Field UI module provides an administrative user interface to the Field
module functionality that works well for the basics, but any earnest use of
fields will quickly run into its limitations. Suppose, for example, that you
are working on a project wherein the node entity portion of the data model is
described by a few dozen content types, a hundred or so different field
definitions, and more than two hundred field instances spread across those
content types. This is not unreasonable once you start thinking about the sort
of Drupal site that supports the Economist, for example, or other similar
business initiatives. Your data model will invariably evolve as the project
progresses, and a great deal of the administrative work flow is defined, or at
least channeled, by the settings in those few hundred field instances: which
widget to use, the messages displayed to the user, which fields are required,
