First thanks for response.

In Worker.addon.nice only methods and "abstracts interfaces" could be 
define it's an addon. see the following example :

// package are define by directory filename instead of directory 
hierarchy, it's because its more easier to see package with a 
filemanager (less click), it's a view ala Eclipse.

prj1/
    src/nice/
       pkg1.pkg11.pk111/
          MyClassA.nice
          MyClassB.nice

prj2/
    lib/
       prj1.jar
    src/nice/
       int.addon.nice //addon to int
       pkg2.pkg22/
          MyClassA.nice // an other class than pkg1.pkg11.pkg111.MyClassA
          MyClassC.nice
       pkg1.pkg11.pkg111
          MyClassA.addon.nice // definition of addons (methods, abstract 
interface) to the MyClassA define in prj1
          MyClassB.nice // => Conflict multiple definition

Now for other developper (than the original), it's easiest to know where 
is the definition of method in the prj2 and where to put extension. Like 
this in one view I could see which class are extended with addon in the 
Project prj2.

When You have project with lot of classes, navigate quickly in the 
source (without scrolling in big file or use IDE search features 
(fulltext, reference or definition)) is very productive.
