Very bad practice.
I define a unit, and i call it a unit, because in all those years of
developing in
VAJ. I don't see packages as a directory structure anymore. A package
is ONE unit and should be treated like that. How it is stored is not
relevant.

But because they filter them out. I can't click on it and say new Class.
We (Eric of Instantiations and i)  had exactly the same problem with there
Plugin.

The strange thing now is when i say: create new package, and i make a
package
that is one less of another then that packages just won't appear. Very
annoying

I think the real solution is just that you specify what the packages are (so
not the other way around)
Just store in a meta file: This and this are packages. And read from that
file.

CodePro already has this. You can switch from on to the other with one
click.
But i am always i the flat mode (VAJ). Because of what i said above that I
don't
see them as a directory structure.
