I think it would be cool if we could choose the # of items we want to review per day.
For example :
80 tones, 80 characters, 80 definitions, 80 readings
Sometimes when I see a large # of items that are due for review, such as 250 or above, I just don't want to even go near it because I know that I probably won't finish it and I don't like starting things I can't finish.
A feature such as this would be very cool. I know that the Skritter guys are busy working on the app, so I'm sure this can't be made available soon, but it would be great to have a few months down the line
