Good Morning Everyone,

my name is Paolo Piccinelli and i'm a rookie in using Pharo. I installed the version 2.0, and I'd like to know what's the difference between a gray and white cube and a totally gray gift box near the name of the Packages. The first kind of cube, does it means that there are some classes missing in the package? Where can i find something about these visual clues?

Thanks in advance for all the explanations.

Best;

Paolo
