Thanks Marxian for taking the time to develop the app. I loved the older version. Unfortunately, issues make the new version quite useless in its current form.
1. "Unable to retrieve video. Access may be restricted." on youtube videos.
2. No option to continue playing the video when minimized/in background/screen off. I assume this is because you use the default video player to play the video.
3. There's no way of going back to cuteTube without swiping out, and no easy way to skip videos in a playlist. When a video starts playing, nothing can be done on cuteTube like queueing the next video. Also, on pressing back/end of video the video player app loads instead of going back to cuteTube
4. I don't see any options to change the youtube playback quality. the only option is normal (upto 360p) AVC1 (less important than the previous issues)

1 is pretty much a showstopper
2 and 3 could be solved by going back to the older method of playing the videos instead of opening it the defult N9 player. Is there a reason you changed to using the default interface?
