[QGIS-Developer] Drill-down (cascading) forms in QGIS Value Relation Widgets crowdfunding

[Andreas Neumann]

Hi Nyall, 

Interesting campaign and definitely some needed feature that will help
further improve forms in QGIS. 

However, I wonder why you chose the "value relation widget" and not the
"relation reference widget". Both widget types have a larger overlap in
functionality and I did hope that we could get rid of one of the two
widgets in the future. Because from a user perspective it is confusing
that different widget types exist that do similar things. 

I had the impression that the team around Denis/Matthias is pushing the
"relation reference widget" and had the plan to implement in the
relation reference widget everything the "value relation widget" does. 

Matthias - please correct me if I am wrong. 

Nyall/Matthias/Denis: What are your thoughts on the redundant
functionality in both widgets? Could we merge the two into one widget? 

Greetings,
Andreas
