[henshin-dev] Hidden-attribute in TransformationUnit ?

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi,

shall we add a Boolean attribute "hidden" to TransformationUnit? If set, 
editors should not display the unit on the top-level of the 
transformation unit (unless a "Show hidden units" action is invoked in 
the context menu). This could be a way to help the users not to get lost 
when editing large transformations.

Cheers,
Christian
