* A way to tell your own cell from the others. In the NW the notice says you have to be in your cell in order for the time to count. I don't know if it actually makes a difference if you're in your own cell or not but if it does it'd be nice to be able to know for certain if you're in the right one.
* Time remaining check. I heard there was a message after you served a day telling you how long was remaining but I haven't seen one so far. Without a way to assure I returned to my own cell (though I'm pretty sure I did). I can't tell if that is the problem or not. Either way, it'd be nice to know at any given time.
