Me too. To Show & Hide the models is absolutely necessary.
And it would be even better if you could additively hide all parts at once and then choose & show the desired ones.
I'd whish to have the possibility to print out the process-settings, that I am actual using.

For instance when I'm testing different settings for a difficult and complex 3D-printout, this would be absolut helpfull.
