What functionality is missing? What is unsatisfying with the current situation?

At the moment, advanced writers and regular writers can create relationships and other guild-only features while in a guild member's world. However, they cannot later edit them, as that requires access to a relationship page, as opposed to the popup that appears when first creating it.   

How does this feature request address the current situation?

This allows world contributors to first lay out their plans, and then fill in the details afterwards, as opposed to needing to get everything right on the first try in the popup menu.  

What are other uses for this feature request?

This is a general improvement of contributor experience, who in some cases are less familiar with worldanvil.
