Here's an idea. I'm not sure it's even possible:
I would like to order my postinfo categories and tags in a certain order. By default it's alphabetically, but it is possible to make it custom? My vision is a field in the Atahualpa post options when I am editing/writing the post, where I can enter cats and tags in the order (by ID) I want to display them, e.g. 'Enter categories to display: 312,567,886,...' It's just about structuring my cats and tags so it's easier for my readers to find related cats and tags. Or is this already possible today, via php?
