// @namespace    https://github.com/SineObama/bilibili-player-auto-set-playtype
// @homepage     https://github.com/SineObama/bilibili-player-auto-set-playtype
// @version      0.1.2
// @description  B站的多数页面中，自动切集功能在播放器里，修改起来很麻烦，所以按照我的习惯做了在不同页面自动切换的功能（脚本运行后可在存储中修改配置），具体包括：1.【自己的收藏等列表页面】自动连播；2.【普通视频/稍后再看/番剧】不自动连播；3.其余情况默认也不自动连播。【吐槽】视频或番剧看完可能会想看评论区，或者点赞等，所以不想自动连播，尤其是番剧最新一集播完可能连播到奇怪的视频。
