Hi there,

Having an auto-fullscreen switch would be interesting and that's something we have not thought of doing but if enough people are interested then we could think about how to implement that.

As for Android, we're working on that as well! Apologies for the inconvenience there. The mobile website of Guitartricks works really well if you want an alternative to using the app on your phone.

For spb1122,

There is no NEXT lesson button because most people jump from lesson to lesson. But for you, I suggest logging in, pressing LAST LESSON, and then when that loads up, press NEXT LESSON on the video page. But a NEXT LESSON button can be an interesting idea as well!

Thank you for all the feedback!
