Per-device subtitle state

Hello,

I’d like to request please per-device local subtitles states. Currently, if you turn on a local subtitle for an item, such as a TV episode, the subtitle will remain on for all devices and persist after the item is “watched” until it is manually switched off. I’d like the option to switch on local subtitles only for a certain device, say; only on a mobile phone with a crappy speaker in a noisy place, and not have them then automatically display i.e., on my TV at home, and vice-versa.

Also, a related request, at least on the mobile Android player, to have the option to “Start all videos with local subtitles enabled on this device”.

Thank you!
