Current behavior:
When new cards are reviewed and marked as "I remember," they are added to tomorrow's "Due today" list. These cards then appear in the "Due today" list in the same sequential order in which they were initially reviewed from the "New cards" section on the previous day.
Recommendation:
I recommend implementing an option or default behavior for cards in the "Due today" list (that were new cards the previous day) to appear in a random order instead of the order they were reviewed from the "New cards" section on the previous day.
Seems like the shuffle button is only displayed on the desktop app. I'll update the mobile apps to include it as well.
