When configuring a Relation, the default view currently applies to both Web and the Mobile App.
In real usage, this is limiting.
On desktop, Table view is usually the best option (density, scanning, editing).
On mobile, List or Gallery views work much better.
Right now, we can only choose a single default view.
Being able to define one default view for Web and another for the Mobile App would be a small change with a big impact on usability
