matchbox and that old admin folder question

[eluser]hyperfire[/eluser]
Hi there

Im kinda new to CI, but reading the forum i have found that if i use matchbox along with ci, i could use a structure like this:

modules
-- admin
-----blog (blog administration)
-------controller
---------blog.php {lib etc ....}
-------model
---------blogmodel.php {add edit del ....}
-------view
---------blog_view.php {list all blog posts)
--blog (frontend)
----controller
------blog.php { list blog posts for common user }

What am i doing wrong, because i cannot make it work here, any ideas please?

And why not support those simple folder structures by default?

Thanks
