pdf expert for mac是Readdle开发团队推出了第一个最好用的PDF编辑器桌面端。就算你手机端用的再溜，工作起来还是使用桌面端更高效。PDF Expert是一个快速，美观的工具，可以增强您的PDF工作流程。 从您选择的第一个文档开始，PDF Expert将通过平滑滚动和快速搜索进行操作。 PDF即时打开，无论它们是小邮件附件还是2000页报告。刚开始使用PDF Expert，您不会感觉到陌生。您可以明显地发现，它的界面显示布局和系统原生的预览.app类似。不过，PDF Expert在预览.app的基础上，做了一些改进和优化。正常浏览模式下，将使用频率较高的按钮都放到界面顶部，左侧是导航栏，可分别切换显示书签、大纲、批注和缩略图。右侧是正文显示区域，当屏幕较窄时，点击左上角的边栏按钮隐藏左侧边栏，可给正文区域提供更多的显示空间。并且支持打开多个标签栏，避免窗口拥挤的同时又能提高工作效率。

Paste Mac 激活版 是Mac os系统上剪切板管理工具，Paste在剪切板界面采用了卡片式的设计风格，每一段保存的剪切内容都以独立的卡片形式存在，并显示相应的应用来源和内容预览。在应用来源这里，还会根据应用的图标颜色，提取出主色彩作为填充色。整体上，无论是设计风格、动画效果，都仿佛是系统原生功能一般，融合度非常之高。

很好的局域网内部扫描工具，对开发，运维都很实用。 解压密码：xclient.info

Application Loader是一个苹果app专用的上传工具，在使用xcode上传失败时可以尝试使用该工具上传到appstore

TouchSlider滑动插件支持手机及pc端，非常不错，支持水平以及垂直滑动等等

一个非常不错的滑动插件兼容pc和移动端推荐使用，里面附有说明文档链接

教育题材手绘黑板报模板，模板颜色为蓝色，带有网格辅助线，模板自带45个手绘icon图标非常漂亮

这是一个医疗录入系统的html模板，请有需要的朋友下载

下载你从不后悔，此套模板为静态html代码，请有一定基础的基友下载

知道的都应该明白，不知道的请自行百度谢谢 23种设计模式 194张图表 57张UML类图 通俗易懂 专业实用
