Issue #560962 by jcmarco, add fieldset tabs configuration based on content type. Also implementing hook_content_extra_fields() for tabset weighting.

Issue #178607, introduce option to put all additional fields (e.g. node title and body) on their own tab.

Initial commit of a module for displaying CCK fieldgroups in tabs. Enables splitting up content onto tabs in both editing and display. Requires DRUPAL-5 version of tabs module (part of jstools).
