Request: Option to use system orientation for rotation.

[AeliusSaionji]

Nothing special, just support for the way apps normally rotate. Respect systemwide auto rotate on/off.

Probably would be named Automatic (system).

I assume that this isn't already here because global auto rotate can be annoying. Ironically this is exactly why I'm requesting the feature: I don't want auto rotation, not even in next player. Without support for system orientation, the existing options are suboptimal (for me):

• App sensor: high chance to start playback in landscape when I didn't mean to, and walking around with phone or just laying flat on a table frequently triggers a 180° flip, which also causes next player to drop audio for a moment.
• always force an orientation: not desireable on phone.
• toggle orientation manually with osd button: it's a small target on my dpi, and the osd autohides quickly- which I otherwise do want to happen.
• orientation based on video: unfortunately this means the orientation of playback controls, gestures, and generally how I'm expected to hold the phone is frequently unpredictable.

Modern Android has a built in solution already: fixed, but a "toggle orientation" button appears when phone is tilted. This is a nice solution:

• No accidental rotations
• nice easy tap target that appears when you (may) want to rotate
• tap target is otherwise not obtrusive if you don't want to rotate.

I believe apps see this as the conventional systemwide auto rotation, so special support isn't necessary.

I also have a more custom solution where I use a quick accelerometer gesture to toggle orientation.

And of course there's the quick tile to toggle auto rotation, and many other backend methods the user may implement to control rotation.

Unfortunately since Next player doesn't respect the system orientation, it finds itself opting out of these many solutions.

Please and thank you!
