I am of the opinion that as Unterganger pages changes quite frequently, it'd be quite inconvenient to explicitly add Unterganger-related categories. But that's not the full problem. The real problem is that more often than not people would forget to remove obsolete categories because they're at the very end of pages, and if you're using the old Editor, they're tucked away in a hardly-noticeable module.
I've gone to great lengths to address this issue by letting the unterganger infobox do the categorizing work. Firstly, it knows exactly which categories to apply. Secondly, change is instantaneous and seamless. Most importantly, infoboxes are the first thing on a page and you'll never miss it.
I admit there have been technical mishaps in how it was implemented, but I'm confident now that the implicit categorizing system within the template is robust enough.
I therefore would like your cooperation with hard-categorizing unterganger pages sparingly. Instead, if the implicit categories seem off, inform me so that I can improve them. Thanks in advance.
