already have done that
and just to simply put it
when you say start main at category = 0 (top category) that is essentially exactly what i am saying
if you looked through all databases you won't find this hence this is
master category with category_id = 0
on the same principle i believe there is one for this too.
and to support my arugument database table category_configuration_id does represent group category id for FEATUREd to be #22 but for some strange reason this logic is not working
or i am on lines in opposite directions
