oh. Yes - I do recognise what you mean. Yes, correct - the categories have been reduced quite a bit and there is a lot of 'white space' on the overview page which could actually be supplemented with more information such as more (sub)categories.
How to achieve a different presentation with more content is beyond my knowledge. Unfortunately I cannot help any further. But I hope that someone from Apple's changeover team is reading this and can initiate further adjustments accordingly. I would also definitely support this if there were even more categories (and they should also be more technical) on the entry page.
Follow-up: I would suggest that you create a specific new post with this topic to attract more attention and focus.
