Yes. (In French, we put the first name in first position, then the family name in last 
)
For example the greg gorman method to BN convertion or the Orton effect.
But you will have too much work tranforming every effect that populates internet to a correct workflow in darktable 
But for artistic effects, you can select that module and apply it at the end, as you told me.
So the problem of artistic effects does not exist: just apply them after filmic or base curve.
For focusing you have contrast equalizer with superior results.
And for the typical high pass with small radius that you apply using linear or soft light painting the mask where you want to improve textures?
What would you recommend?
I guess that local contrast or a contrast equalizer module applying just border contrast to high frequencies would do.
Great to know that the interface is going to change accordingly to better reflect the current workflow and give more insight about when a module is applied and the expected color space.
Spanish too. So I suppose Aurélien was the name, but Pierre sounds as a name to me too (Peter or Pedro).
