Classes removing and renaming best practice with Atelier

Hi!

Suppose I have a project in Atelier with two classes: Class A and Class B and develop it in my local Caché installation. 

If I decide to delete Class A and delete it in Atelier project will it be deleted in Caché automatically or should I do it manually?

Or what is the suggested workflow in this case?

Same question is if I decide to rename Class B to Class C.
