Hi José, yes that makes perfectly sense.
Perhaps one of the bigger brains has a firm grip on how to solve this issue, but, to me, there’s nothing that will make this process fool-proof - except (and certainly when working in teams) for tight work-flow control and good procedures.
Requiring that everybody in the team saves a layer state when a detail is finished, and then requiring that everybody restores the layer state before printing could be a good procedure and might even be scriptable.
But, remember that ,even if detail layers had a life on their own (which, as you stated further above, is on the wish list), if a user adds a new layer with a new object, this will be visible in every detail on all layouts. And, yes, layer states will not help here either.
