We can associated multiple categories with WP entries. But the categories are displayed in the post in the order of their numeric ID. It would add more meaning to the post if the categories were displayed in the order in which they were selected by the author. Example: selecting the primary category, then 1 or 2 sub-categories.
As WP currently operates, there is no indication which of the three is the primary category, i.e.: if the primary category's ID# is after teh sub-category, it is display "out of order".
Is this possible? Is this of interest to anyone but me?
