-## 🔥New feature：GuiLite previewer(WYSIWYG extension for GuiLite)
-- [GuiLite Previewer](https://github.com/idea4good/GuiLitePreviewer) is a Visual Studio Code extension, could extract GUI information from C++ code and preview GUI at preview page(What you see is what you get)
-- No need for drag-and-drop widgets, everything (e.g. code/design/build/debug) could be done by coding
-- No need for special GUI editor(e.g. Android Studio, Qt designer)
-- No need for Extensible Markup Language(e.g. xml, xaml)

-- [GuiLite Previewer](https://github.com/idea4good/GuiLitePreviewer)是一个Visual Studio Code插件，它可以自动提取源代码的GUI布局信息，并实时显示在“预览”页面上(所见即所得)
-- **不需要**“拖拽”控件，仅通过敲代码，就可以完成所有工作（例如：代码，UI编辑，编译，运行，调试）
-- **不需要**使用庞大的GUI编辑工具（或IDE，例如：Android Studio, Qt designer）
-- **不需要**使用可扩展标记语言（例如：xml, xaml）
