That's ... exactly what the subscriptions feed does right now?
My subscription feed now has a row of 3 videos labeled "priority", then a row of 3 videos labeled "latest", then a row of "Shorts," then it appears to continue on with the "latest" but there's no label.
This is from memory so I may have got something wrong. And I could be an A/B test subject as this has been new as of a few weeks. There's also a "More..." fold or two in there.
This pattern does not represent how I use the product. I do not watch shorts and I don't know how or why they mark things as a priority. I want to know what's newest and the time ordered list being deprioritized in the UI and fractured makes that worse.
The subscriptions page was changed about a month ago. It now shows the videos in the top as "Relevant", which includes a list of videos from the ~12 days that are being suggested to you. After that is a real list of chronologically ordered videos, but videos are not listed twice. This means if the video appears in the first list (as "relevant") then it will not be shown in the second list.
The end result is that the subscriptions page now shows videos "in order", but the order is wrong. My current subscription page shows a video from 14 hours ago, then a video from 9 days ago, then one from 5 days ago, then 6 days ago, and then 1 day ago.
Honestly, I feel like `yt-dlp` does a better job of this with this command:
