AHAH Edit Node In Place
This project is not covered by Drupal’s security advisory policy.
UPDATE: I can no longer support this module as my day job no longer involves Drupal development. If anyone wants to take over development, let me knpw.
Provides both the API and UI to enable in-place editing of node fields. Currently, UI only supports CCK and the node body, but the API may be used in combination with the theming system to enable editing of virtually any node field.
The module works by only fetching the relevant parts of the Node Form for each edited field (or field group), via AHAH (hence the name), and takes care of reloading only the changed data once the form has been submitted (also via AHAH).
