I may be interested but what is important is to keep a default setup where the current boxes are still visible and at same place than current version, even after a first install, so user immediatly know he have main information on home page.
We must keep layout to be first part is 2 columns, on of 30%, the other of 70% so we can put small boxes on left, and large array on right and a second part (under) that is 50%/50%
The boxes are defined into the $this->boxes array of module descriptor files. They are stored into database when module is enabled.
But what i am most interested in, is to have support for boxes (with same layer 30%/70% and 50/50% under) on other top menu.
