I am thinking of the following approach.  When in concept mapping
mode, each time we create a sibling, we can create an intermediary
node without outline with splines on either side  Whenever we need to
create a crow-feet, we can select the label created as above followed
by inserting a normal sibling without an intermediary node.  Here we
interpret a regular concept node without an outline and background
color as a link.  What do you think?
