I am coming from a github issue from where I was redirected here ( feat(card-browser): new UI to select sort order by david-allison · Pull Request #20240 · ankidroid/Anki-Android · GitHub ). This is what I wrote there (minor edits for clarity):
When sorting by Due date or Interval, I think it would make sense to use a different sorting method for New cards within that sorting option. Since a card with a fixed due date and a card without one cannot be properly compared, I think treating New cards differently is warranted/helpful.
What I suggest here is to always put the New cards at the bottom when sorting by Due or Interval, no matter the sort order.
The rationale is this:
If I am interested in cards that will come up soon, I do not want to scroll through all the cards I have not seen yet. The same applies the other way around: If I am interested in the cards that I haven’t seen in a long time, I am also not interested in the cards I have never seen.
This idea comes from a specific workflow: I have downloaded a deck that I want to annotate with custom mnemonics, especially for cards that I recently got wrong. Since this is a lot of work, I want to do this bit by bit, focusing on the cards that I struggle with currently. For that, I need to sort the deck by due date, so I can see the closest cards first. Currently this leads to a long list of New cards coming before the Due cards, which forces me to scroll through all the New cards before I get where I need to be.
I also thought about whether there might be a use case similar to mine that requires to see specifically the New cards first. If such a use case exists, I think it could become a different sorting option that sorts the New cards in the order that they would be shown in Anki, always followed be the non-New cards, no matter the sorting order. So we would have the exinsting sorting paradigms for Due and Interval (slightly modified), and a separate sorting paradigm for New cards (sort by their internal order). I think this would be cleaner and solve the issue that Due and New cannot be properly compared.
Even if a new sorting option for New cards is not relevant, I would argue that changing the sort order in the Due and Interval options is.
