I agree with Rachel. Not all of us are using or will use the apps.
Please adjust the website version to have a "light theme". The current display is very hard on aging eyes and the other colours used to emphasize or redirect are nearly impossible to read.
Please see the About Forums section for an example of this.
Having said that, I am enjoying the new format. Improvements like "speed control" and being able to stop "autoplay" for the next lesson would be much appreciated. Please consider these improvements in near future updates to the website version.
