- 图例跟随重命名：绘图区图例文本改用信号当前显示名（Title）， 左侧列表改名后网格图例立即同步。 - 标签页重排与改名：新增拖拽排序（按住标签左右拖动并显示插入指示条， 重排后保持原激活页）与双击内联改名，新增 MoveTab 正确处理激活下标。 修复改名后未重新布局导致标签页整条消失的问题（SetTabs 会重置标签矩形）。 双击判定改为自行按双击时间识别，不再依赖系统 WM_LBUTTONDBLCLK。 - 信号拖拽：虚影改用原信号颜色与线宽（不再画成虚线），保持原有线段/散点样式； 横向与纵向均自由跟随鼠标位移；拖拽首帧位移为零，虚影始终贴合在鼠标下方。 - 网格与标尺细化：时间轴与幅值轴期望刻度数提高，并在相邻主刻度之间 补绘 5 等分细线，便于目视估读。 - 图例定位与交互：图例移到各网格左上角，与标尺数字冲突时优先显示图例 （标尺数值主动避让）；图例条目支持单击选中信号（与左侧列表联动、 样式区随之切换目标）与双击重命名信号。 - 网格划分：合并网格后新勾选的信号不再被并入那个唯一的合并网格， 而是自动切换为自定义划分并独占一个新网格。 - 工具栏：「每信号一格」改名为「拆分信号网格」。 - 清理：移除已无引用的 UiDrawArrowIcon 与 m_styleContentRect。
