Nice work. "10 Seconds" is a pretty odd default for Time Estimate, I can't think of too many things I'd bother writing down that take 10 minutes to complete. I'd go with something longer, 15-25 minutes [<a href="http://en.wikipedia.org/wiki/Pomodoro_Technique" rel="nofollow">http://en.wikipedia.org/wiki/Pomodoro_Technique</a>].
