After the Feedback from J Palotay and the update of Space:Banat_Location_Categories (as well as the bookmarklet and WikiTree BEE to help with category creation from Wikipedia) the Category: Banat is completely cleaned up, it only has counties underneath it. The counties only contain subcategories that fit to the country; the Hungarian counties have only Magyarország categories, while the Romanian and Serbian ones only have their country as suffix.
Next would be Category: Batschka, I don't know exactly how to proceed there: The bigger part is situated in Serbia, where we currently have no county categories (and I only very low ambition to create those). So there is basically no container to collect all Serbian categories that would qualify for placement in Batschka category, since all are in the Vojvodina category, that also contains the Banat villages.
On the other hand, the term Batschka is already German, so maybe it would be an idea to place the German ", Serbien" categories in there. Do I assume correctly, that Category: Bács-Bodrog vármegye basically covers the whole Batschka area as well? Then it could be used as a synonymous category with an aka link.
Additionally there are some 600 profiles in there, where the majority might be gone after moving them to Category: Bačko Dobro Polje, Srbija (hint: the current preview version of WikiTree Browser Extension contains the new feature Category Management, which allows batch categorization of profiles, feel free to try it out on those profiles).
