Hi,
Visibility is expected like this. In theory, you have 3 options when adding a new track after the configurations were created in the project:
A) Show the track in all configurations.
B) Hide the track in all configurations.
C) Bother the user by defining if this track should be visible/hidden in every single one configuration.
D) Bring an AI to decide if the track should / or not be visible in every single configuration.
To me A seems to be to best solution, the least risky (I don’t want to add a track, which would become hidden immediately) and the least bothering me.
