On list sub-sections, sometimes when you complete a sub-section it says "Done 9/27/11" (or whatever the date is), and sometimes it doesn't, even if you've studied all the words in it and haven't gotten any wrong. What exactly is triggering the "done" tag here, and how do I make sure it shows up when I'm done with a sub-section?
I ask because I made a list that gives me a certain number of characters to study every day, and it's satisfying to see that I actually got the day's studying done for that date, but it's going to look like I slacked off today even though I didn't. And that bugs me so much that I'm about to nuke all my progress and start over, since I'm only a couple days in.
