these tools allow to make hard surface sculpt with ease and great results, it would be incredible to have them. Please I beg you to add them.
Oh I almost forget , something like Surface noise too, the deformers (Polish, Clay polish) and this surface noise should be applicable to the entire mesh or unmasked areas .
with a noised mesh you could boolean substract it from and other mesh to get some cool broken concrete effect for example.
Best regards.
