Hi J, I must admit, that I wasn't aware that there is such a complete historical structure below Category: Kingdom of Hungary and its Hungarian counterpart, since I only saw the mess of languages in Category: Banat and Category: Batschka, where there are barely categories with suffix Magyarország. This suffix, on the other hand, doesn't contain the word Kingdom and therefore makes it impossible to separate formerly Hungarian places from the current ones, without having to check the parent categories. This I also do not consider a good solution.
On the other hand I also have to admit that there are - if the count is correct, almost 1600 categories below that Kingdom category and that it would be a lot of effort, now to rename those. Also it would then lead to the requirement of having two categories also for the "still Hungarian" places, which also seems a bit too much, in my opinion.
My original intention was to get rid of the language mess in the Banat category. As one can see at the query link above, language mess is a fact in those categories. There are some German ones, some Slovakian ones and some English ones. Those should be moved out of there and should be replaced by duplicates with ", Magyarország" and linked via the aka template like it is done in Banat now.
This also implies, that the subcategories of Category: Szerbia should no longer also be in the historical county categories like Torontál vármegye as well.
So the goal should be, to only have ", Magyarország" categories in there and those should be linked to the present-day categories via the aka template as well, so the category content gets synced and all categories contain all profiles.
I will then try to adapt the bookmarklet and WikiTree BEE, so also be able to create ", Magyarország" categories and to no longer include the historical county in the present-day Serbian/Romanian category. I hope this fits your needs?
Having to do those changes now, when there are over 100 Szerbia categories in place already, is pretty frustrating for me. I was thinking that you meanwhile were ok with the suggestion, since after your initial reply there was no reaction from you to the comments that were afterwards. Anyways, better late than never.
