Hi guys,
I think it is a good idea to could update a data view of an object with the new added attributes to the object, with one button "update object with new attributes". On this way we don't have to drag from the connector.
Than the modeller could may update automatically the data view with the new attributes of the object (all attributes - yet added attributes).
The attributes which are excluded purposely could may be detected due their creation date in order to exclude them also in the update ...
