When question is displayed (regardless if single or in list) question header contains category where it belongs to.
Problem is if that is subcategory it displays only subcategory name. If there are different subcategories in various categories but having same name that leads to confusion.
I would like to change it to display not only category name, but parent categories names too.
I would like to make it as plugin.
I've spend quite number of hours inspecting code but cannot get to the right track. This part of site is handled by code which is quite generalized and hard to follow.
Can I get any clues how to do it?
