Generate table of contents for any website. By default, it is not open. You need to go to the plug-in menu to open the switch for the website that wants to open the toc. The plug-in will remember this switch, and the toc will be generated automatically according to the switch when you open the website the next time.

// @description:zh-cn 可以为任何网站生成TOC网站目录大纲, 默认是不打开的, 需要去插件菜单里为想要打开 toc 的网站开启开关, 插件会记住这个开关, 下回再打开这个网站会自动根据开关来生成 toc 与否. 高级技巧: 单击TOC拖动栏可以自动折叠 TOC, 双击TOC拖动栏可以关闭 TOC .
