On links, shift position where arrows meet

[sirjeannot]

Is your feature request related to a problem? Please describe. For readibility, it would be a plus to be able to move where the arrows meet.

Describe the solution/feature you'd like A percentage slider position on the link attributes to move the point is sufficient. Similar to the slider to move where the queried text is displayed.

Additional context It would be a plus especially when using vias/connecting nodes, the 'other side' is only on the very last leg. moving the meeting point further from the last node helps readability. Super plus, for link with multiple vias, moving this meeting point to the 'middle' link so the link itself is more balanced between the A and Z side queries.

Thank you.
