It would be nice if when it’s time to review, it does it 10, 20, 30, or x number of items at a time instead of all of the items you have to review. Kinda like how when you hit lessons, you get 5 at a time, why not do the same for review items too? That way you spend 10 mins on 30 items, break. Go for another 30 items, break.
I usually just stop after I do like 20 items but sometimes an item will be tested on the Japanese or English side, and the other half won’t show up until at the end of all of the review items.
I saw another topic of a similar idea but it’s been archived now.
