Pauses when hidden被遮住就暫停
Windows covering the desktop or a full-screen app? Playback stops.視窗蓋滿桌面或開啟全螢幕 App 時自動停止播放。
Respects your battery顧及電池
Pauses in Low Power Mode, on battery (optional), and when the screen is locked or asleep.低耗電模式、使用電池時（可選）、螢幕鎖定或休眠時都會暫停。
One decoder, every screen多螢幕只解碼一次
A single shared player drives all displays, so extra monitors cost almost nothing.所有螢幕共用一個播放器，多接螢幕幾乎不增加負擔。
