Hi, thanks for your reply.
By the way, are there any reasons for you to have the filter to be on a specific ordering since these filters are only used on the back end?
Yes, because keeping a clean and unchanging structure is key if you have > 300 posts in different categories.
Therefore the category filter dropdown should follow the category tree.
It would even better to have the feature to display every post from a certain category, even if the post belongs to a sub-category.
I think that the backend is based on the principle of displaying everything and then using the search or the category dropdown.
This is maybe good enough for a lot of blogs, but if you want to use a deeper structure for your blog, you are going to have hard times with the current blog posts backend. (But that is someting for the feature request forum.)
