I would like some good refactorings in my browser. I tried to get the
OBProtocolBrowser on the SqueakSource repo. But it says I lack a lot
of repositories. I search for OBCommand, tried to load it, depends on
others...
I there a global package to load somewhere ?

You might not have OmniBrowser installed. You want -

* OB-Standard
* OmniBrowser
* OB-Morphic
