// @name 🚀哔哩哔哩（bilibili)倍速与多P剩余时长显示增强脚本
// @namespace http://tampermonkey
// @version 2.7
// @description  🌟让您的b站（bilibili，哔哩哔哩）视频观看更加轻松愉快！本脚本支持：⭐倍速播放：按下 "Z" 恢复默认速度， "X" 降低速度， "C" 加快速度⭐显示多 P 视频的剩余时间,让您掌握自己的观看进度，随时调整观看计划！⭐屏蔽adblock导致的提示框，快来试试吧！🎉
// @updateNote   v2.7 - 菜单项增加了「启用/禁用记忆倍速」功能。
// @updateNote   v2.6 - 修复了切换视频时间统计不更新的问题。
// @updateNote   v2.5 - 修复了视频跳转、页面显示相关问题。
// @updateNote   v2.4 - 修复了某些情况下多P失效的问题。
// @updateNote   v2.3 - 现在按下 'Z' 键可以切换默认倍速和记忆倍速，修复了某些情况下倍速失效的问题。
// @updateNote   v2.2 - 速度调节提示框位置优化，屏蔽adblock提示。
// @updateNote   v2.1 - 倍速步长调节（默认0.1），倍速功能启用/禁用，多P视频信息剩余时间展示启用/禁用。
// @updateNote   v2.0 - 增加了倍速功能，每次步进为0.25，记忆上一次播放速度，优化多P视频信息剩余时间计算性能，修复了已知的一些问题，提高了脚本的稳定性和兼容性。
// @updateNote   v1.1 - 开源协议调整。
// @updateNote   v1.0 - 第一版发布，多P视频的剩余时间显示。
