Thank you Tim, then I will not use maximum.

What is exactly the difference between none, minimum and maximum simplification?
Better said, for none and maximum it is clear, but where is the limit between minimum and maximum?

The user manual says only (page 55) "Minimum: do basic simplifications"
By the way in the figure at the bottom of page 55 the "simplify" menu is missing.

Thank you very much for the help !
