I have to agree with you on this. I just downloaded my first magazine style theme (Mimbo) and am going through the tutorial, and of course, can’t find the category ID. I had to go to the database and really dig for it. I think that’s pretty dangerous and totally unnecessary, since it was so easy to find before. Hope this was just an oversite on someone’s part, or enough people complain enough that it gets reverted back to being able to find the id in the backend.
How frustrating….
