First, I have now been using LingQ for 6 months and find it to be an indispensable tool for language acquisition. I only became aware of the Comprehensible Input Hypothesis this year and have now experienced its efficacy first hand. Using LingQ to manage CI has increased the rate of my acquisition by leaps and bounds. I only wish I had known about it before, because it has become painfully apparent how much time and effort I spent on a prior language using standard methods.
As for the request, it would be highly beneficial to have a Previous and Next button on the Import Lesson page (to the left of the Save and to the right of the Save & Open button respectively) for those of us who create Courses with large numbers of Lessons. When sequentially editing a Course (e.g., adding MP3s after creating Lessons), it becomes ineffective and a bit arduous to scroll down the Lesson list time and time again, which, I am sure, is exacerbated by the fact that my eyesight is no longer what it used to be.
Regardless, thank you all for the wonderful tool. I look forward to years of use and many more languages to come.
