You mention funding this feature previously … what about funding a custom shortcode option that’ll meet your needs. I can write an extension for Connections that’ll add a new shortcode option that could custom order the categories. Simply you would add the category ID/s in the order you wish to have them presented. The only limitations that I can think of is that only the categories listed in the order would be included, meaning any category listed would not be displayed at all. And the listed categories would not be presented in a hierarchy, which from you description of you needs thus far would not be a problem.
