- 运行区：编译错误、运行异常、控制台输出和保存的图片移到窗体下面，不再被实训台挤成 0 高；缩放和放大按钮移到桌面上方，不压窗体的关闭按钮；放大后也能停止程序；点停止后清掉窗体 - 运行异常：常见 .NET 异常配中文说明，显示出错的文件、行号和方法，点击跳到代码 - 运行中的下拉列表挂到页面最外层，能伸出窗体和分组框（小窗体也能选到 COM4、COM5） - 学生登录后进"我的作业"；任务面板从工具栏下面开始，不挡导航；记住上次做的实验，从数据库页面返回、恢复数据时默认用它 - 代码页和设计页左栏都占 3/5，文件标签放不下时换行；实验选择框加宽；关闭粘性滚动 - 设计器：双击生成的事件方法带缩进；双击工具箱放进选中控件所在的容器并错开位置；新控件比容器宽时按比例缩小；无边框窗体不画标题栏 - 中文界面：代码编辑器（查找替换等）、属性窗口的颜色选项 - SQL：DATEADD、DATEDIFF、DATEPART 的日期单位（day、hour）解析成 IdentifierLiteral 时报"不支持"，补上 - 项目 8 的预置环境数据改成建库那天之前的 7 天；p6-t3 评分项改为"按日期查询环境数据" - 没有 AI 建议时不显示"全部采纳 AI 建议"和相关说明；导出 CSV 只给纯数字的文字加制表符 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
