while Portrait playback is a welcomed feature, I find it rather "fiddly" for my own usage.

For example, while I am lying down watching a video on landscape, an "accidental" flip on the device made it goes to portrait mode. So if I rotate it back to "landscape", it will be in minimized mode until I press full screen again.

I wished that "full landscape" mode (on video) can be the default viewing behavior until I pressed the "minimize button", then I can go portrait or landscape mode which ever way I want.
