Improve IObservables: rely on Nested Transactions to simplify the implementation (Mainly for Transactional IObservableLists which are currently a nightmare to implement & maintain) Support Multi-selection of multi-valued properties (Stereotypes application, Styles, Mask Label, ...) Add shortcuts in the metamodel, especially for elements which are not meant to be reused (Ability to bypass the environment model for very specific widgets/model elements) Allows faster prototyping, at the cost of reusability Integrate with ElementTypes for creation of new elements Improve support for properties navigation (Easily edit self.a.b) Support widget substitution, to replace e.g. all Boolean Radios with Boolean Checkboxes (With a scope, e.g. “only in the context of such language or property”)
