Until now, every workspace started with the generic Juristic standard "Default" relationship you couldn't change, including its arrow, colour, and edge type.

An admin can go to the admin panel and pick any relationship from your firm's library to set as your organisation's new default. From then on, the "Default" entry at the top of the Relationships panel looks and behaves exactly like the one you chose, with the same arrow, colour, and edge type, and every new line you draw uses it automatically.

If your admin hasn't set one yet, nothing changes.

Only organisation admins can change this, and it applies to everyone at once.
