+- <span  style="color:red">国内可以直接使用newbing (chatgpt)</span>
 - 微：不到200K。
 - 威：支持使用js脚本、url服务、shell命令、内部功能链接定制菜单／（新）按钮／手势; 远程数据皆可成网站。html5应用增强，可匹配本地应用。
 - 便捷：图书（pdf/djvu）/txt/词典（mdict,kiwix）/命令行/APP/webapp(web extensions)可作为搜索引擎使用。
 - 快：手机越慢，脚本插件越多越明显。
 - 高效：最少的操作，在线服务全自动（参看常用链接网页）。
-- 极致优化：
+- 极致优化：最少存储写操作，比如浏览器转到后台前配置变化如恢复成原样则无写操作。
 - 地址栏支持命令行 ("!", 物理键盘支持更佳)
 - 指定域名: 用户定义JS/CSS/HTML/显示前源码预处理
