TYPO3 Page- and Contentelement Wizard

Creating form masks for content-elements and page-templates with dynamic form fields is a complex thing to do in TYPO3. The popular extension "TemplaVoila" made this a lot easier, but "TemplaVoila" became outdated over the years and has some major disadvantages. We'd like to develop a new extension, which replaces the old fashioned way of using TemplaVoila and uses state-of-the-art techniques. A prototype already exists.
