I love the extra study newly learned widget, and the fact that the curriculum now has a ton of vocab. Unfortunately, both of these things combined means I have 50 items in the recently learned queue. At 50 items in the widget, I think it might actually be better to just accept that my review scores will be low, and therefor have +10-20 extra items per review. OTOH, if we were able to study by item type, I could target the newish 12 hanzi (I learn 6 per day). I find that words are much easier because the reading is basically free, and the meanings are usually guessable if you know the requisite characters. This could also apply to the recent mistakes widget.
Also for both widgets, it would additionally be useful to optionally remove items you have already answered correctly in a review from the study session .
