Right ok - think I’m on the right path now. Looks like I should be able to set the necessary modules to ‘legacy view’ as you’ve mentioned and then customise the view and edit screens separately. This looks helpful

It seems like an odd choice to have the new UI limited in this way, we have a lot of modules where the edit/create view is different from the detail view, but maybe we’re in the minority
