当前阅读模式似乎只会提取标题、正文和描述字段，而实际上作者和发布时间对于文章来说也是蛮重要的信息。但简阅没有相关字段可以填入匹配规则。希望可以添加相关字段。
如 Firefox 的阅读模式等都会提取作者和发布时间，如 Mozilla 维护的 Readibility.js
会匹配：

    // property is a space-separated list of values
    var propertyPattern = /\s*(dc|dcterm|og|twitter)\s*:\s*(author|creator|description|title|site_name)\s*/gi;

    // name 

At present (probably) adding a new book under a heading just does a single line skip and thus will cause issue when there is description for a section header.

Display a count of how many items there are in the reading list, either on icon or on the list itself (or both).
