@Ricbet 几个可以优化的地方，看是否要在这个提交里一起实现：

1. 初次打开时，可以默认选中一下配置第一项，这样不会出现 NoConfigurations 的情况

2. 样式上：
   • No Configurations 左侧可以适当加一点左边距
   • “Add Configuration” 按钮底部可以适当增加下边距
   • 右侧编辑表单列表同上，底部可增加下边距
   • 打开编辑内容左侧按钮无 “选中态”

3. 可能的优化点

• 对于 variables 后续可以在这里直接帮用户展示出来，一些用户也会疑惑具体指代内容
• 如：[变量 Variable Selection] [文件 Input] ，然后在下面一行展示具体指代文本路径
• 

[Ricbet]

1、2 我优化一下，3 后续再优化

[Ricbet]

• 默认选中第一个配置
• 新增选中态
• 优化部分样式（No Configurations 左侧增加边距，Add Configurations 底部增加边距，右侧add configurations item 底部增加边距）
