Hi Mojca,

Thanks a lot for your mp code, I got what i want but rightnow, I don't 
know how to use it exactly, maybe as follows attached (try to display a 
general progression thru advancement of each courses, and show on the 
same "pane" (inner margin)), list of each chapters.

I'll try to cook a minimal but working example, as I got -- in a messy 
way -- almost everything for bring this new layout to life.
