TYPO3 Extension feeditadvanced provides the new amazing Frontend Editing functionality for the TYPO3 4.3+.
Although it works with the classic templating ideas of TYPO3 ("Modern Template Building"), it also works out of the box with TemplaVoila ("Frontend Editing").
The main feature set is to add new and edit existing content element in the Frontend of TYPO3. Also is possible to edit any other record (tt_news for ex.) in the frontend using feeditadvanced functionality.
This is no replacement for the TYPO3 Backend, as it is solely focused on editors with only limited needs to edit pages and content in TYPO3.
Please take look on video demonstration of this major feature:
