2 quick suggestions, purely from a beginners standpoint.

1. My work/family life is hectic, so I don’t get a super “set” time to study… I do  however try to devote a few (3+) days  to studying (Japanese and school work) turning off all other distractions and going through a lesson of Japanese and then writing in my new Evernote study diary about what I learned…. That being said, why not a way to see what page you last left on or to “save” your state during a lesson.  So if I get stopped halfway through because of life, and I pick it up the next morning (or few days later) when I find a free hour during work, I can log in and remember the exact chapter/page I was on.

2. A online calendar in order to record the days you study… I do this on my own, but something built in might be found more useful to new self paced users so they can track their Study time habits!  Or Have Textfugu auto track how much time/ the days you study so that you can look back at your “history” and plot how much time you have been devoting.

Anyhow, I’m loving it so far, about to complete Season 1, I’m a lifetime member have tried studying Japanese before, but this year (and the next :p) is my year!
