@Harm Horstman I did a couple of tests on this topic for the Universal GUI specifically.
- I manage to hide Detail tabs just fine with the Context procedure after clicking the Add button, by checking on PK column is null
- In combination with a Subject setting Start empty with filter this allows me to start a Subject from a menu without Detail tabs being displayed.
Could you explain your Use Case a little more: what kind of scenario do you have and what UI behavior would you expect related to it?
NOTE: merged one of the Ideas you referred to in another open Idea (which you didn’t mention):
