Make possibility to select 'relations'/'connections' optional in diagram view.

Some customers model their objects and connection very close together and in the diagram view it's then very easy to select a connection instead of the object. Selecting the object can be very difficult and if you are not interested in connection information at all, it would be very helpful if we can make selecting specific items in a diagram optional. In this specific case those items would be the connection in between objects, but other cases could also apply where you perhaps are not interested in specific items on the model and would like to have the 'clickability' disabled. It's easier to select objects if you cannot select the connections in between. Perhaps it can be made configurable.
