請問能夠讓首頁也停止自動播放嗎?
滑鼠停在上面就會自動播放

@leadra 改好了。0.4.0

It seems actually configurable, so I probably remove it in future version.

了解，感謝^^

YouTube幾天前改了什麼，現在這樣移除掉播放器，雖然不會播放，但YouTube仍會以為有播放，會影響觀看紀錄。所以我會正式移除這個功能，之後就自己調整帳號設定。

編輯：我找到了。1.1.2外顯行為將與過去一致，關閉首頁游標懸停時自動播放。主要是這樣沒登入也可以生效，而且那項設定好像也會讓頻道頁面中影片與右側推薦影片不會有懸停時的動圖（非自動播放、不影響觀看紀錄，只有幾幀影格循環的那個）。
