When creating and modifying content types, it can be cumbersome to manually align and check every structure for the different models:
Title of the different property groups
Sequence of content inside each property groups
Plus, some structures are quite standard from one customer to the other and, having the possibility to "plus n play" is missing.
It could be a real value added to be able to extract (XML for eg) the different content types or property groups allowing to reimport them or reuse some parts from one environment to another or in another model type.
