[vwnc] Proper way to add a method to a class outside of namespace?

I am trying to get my head around packages and namespaces (Squeak is
my only Smalltalk).

What is the proper way to add a method to classes outside of my
personal packages? For example, I want to add the message:

Double >> arcTan: denominator (like C's atan2 function)

from Squeak to VW. How do I add that and make sure it is properly
managed with my own package? In Squeak, I could make a protocol with
the same name as my package and this new method would be managed in
Monticello along with the package classes itself. It wasn't clear to
me in the Managing Smalltalk Source Code Chapter of the Application
Manual how to do this without making a mess of the image.

Thanks,

David

One of the option is to create the method anywhere, and them <Move><to
package> via pop up menu.

Another option is to set the Default Package so anything you do ends up
there.

In reply to this post by David Finlayson-4

Click on the class, "Extend in Package ...", select your package as
the target.
