• Player now gets visible only if the play runs, which means if the autoplay fails the player won't hang in there frozen
• State propety, and state events. All are synced with YouTube state changes, though the YouTube instance got a simlated timeupdate event. More on the events usage can be found in the README.md. Solves the issues on: #51
• Duration property of the instances and core functionality for enabling the seek bar constuction
• Added lazyloading option. Thanks for the reminder @jiang-yuan in the issue you submitted #37
• force-on-low-battery, I've got startled that the script didin't work all of a sudden on mobile iOS, turned out I had a low battery... I've added a setting that will run the videos on the first user interaction if enabled so your background can run even if the autoplay is disabled by the low battery.
• Like so many small fixes, renames, moving arround... I've lost count...
