I am going to describe two improvements that I believe are necessary for any professional laminator.
First of all, I think it is necessary to be able to include modifiers for the laminate; sometimes the models have critical points that need more filling or a different configuration without needing to apply it to the entire model.
The other point would be to be able to modify the density of the upper part of the support. Sometimes with a density of 100% it is very difficult to remove the supports.
