TYPO3 Core

It would be great to be able to arrange FlexForm fields in the editor interface as if they would be ordinary TCA columns.

This would remedy a disadvantage of FlexForms (limited backend interface possiblities) while keeping its advantage (a "simple" structured value store within only 1 database column).

This would make it possible to add FlexForm fields to their semantically correct place or mix them into a palette with existing fields.

A use case could be a plugin that allows selection of an output template - this field would be more suited near the existing "Layout" tab/palette than inside an arbitrary section "Plugin Data [pi_flexform]".
