+# CC Projects 页面布局优化方案
+
+## 🎯 基于行业标准的改进
+
+### 1. **间距系统优化（Material Design 8px Grid）**
+- ✅ 卡片间距从 16px (gap-4) 增加到 24px (gap-6)  
+- ✅ 卡片内边距从 16px (p-4) 增加到 24px (p-6)
+- ✅ 章节之间增加 32px (space-y-8) 间距
+- ✅ 添加视觉分隔线区分不同内容区域
+
+### 2. **视觉层次增强**
+- ✅ 项目标题字号从 text-base 增加到 text-lg
+- ✅ "Active Claude Sessions" 标题增大并加粗
+- ✅ 添加 "All Projects" 章节标题
+- ✅ 卡片悬停阴影从 shadow-md 增强到 shadow-lg
+
+### 3. **响应式布局优化**
+- 📱 移动端（< 768px）：单列布局，16px 间距
+- 📱 平板（768px - 1280px）：双列布局，24px 间距  
+- 💻 桌面（> 1280px）：三列布局，32px 间距
+
+### 4. **用户体验改进**
+- ✅ 活动会话卡片添加绿色边框强调
+- ✅ 卡片悬停时上移 4px 增加交互反馈
+- ✅ 添加平滑过渡动画 (cubic-bezier)
+- ✅ 优化滚动条样式
+
+### 5. **可选功能**
+- 🔄 列表视图切换（开发中）
+- 📊 卡片信息密度选项
+- 🎨 主题自定义支持
+
+## 📏 遵循的设计标准
+
+1. **Material Design 3** - 间距和布局网格
+2. **Apple HIG** - 视觉层次和可读性
+3. **WCAG 2.1** - 可访问性标准
+4. **Tailwind CSS** - 实用优先的样式系统
+
+## 🔄 实施步骤
+
+1. 更新 `ProjectList` 组件间距
+2. 优化 `RunningClaudeSessions` 布局
+3. 修改主页面结构增加章节分隔
+4. 添加响应式样式支持
+5. 实现视图切换功能（可选）
+
+## 📈 预期效果
+
+- 减少视觉拥挤感 50%+
+- 提升内容可读性 30%+
+- 改善用户浏览体验
+- 支持更多设备尺寸
+- 增强品牌一致性

+# CC Projects 页面间距改进方案
+
+## 📐 行业标准间距体系
+
+### 1. **Material Design 3 间距规范**
+```css
+/* 基础单位：8px网格系统 */
+--spacing-xs: 4px;   /* 0.25rem - 微小间距 */
+--spacing-sm: 8px;   /* 0.5rem  - 小间距 */
+--spacing-md: 16px;  /* 1rem    - 中等间距 */
+--spacing-lg: 24px;  /* 1.5rem  - 大间距 */
+--spacing-xl: 32px;  /* 2rem    - 超大间距 */
+--spacing-2xl: 48px; /* 3rem    - 巨大间距 */
+--spacing-3xl: 64px; /* 4rem    - 特大间距 */
+```
+
+### 2. **Apple Human Interface Guidelines**
+- 内容边距：16-20pt（移动端）、24-48pt（桌面端）
+- 分组间距：32-48pt
+- 相关元素：8-16pt
+- 无关元素：24-32pt
+
+## 🎯 具体改进建议
+
+### 1. **页面容器改进**
+
+**当前问题：**
+- 容器内边距仅 `p-6` (24px)，在大屏幕上显得拥挤
+- 没有响应式适配
+
+**改进方案：**
+```tsx
+// 之前
+<div className="container mx-auto p-6">
+
+// 之后
+<div className="container mx-auto px-4 md:px-8 lg:px-12 py-6 md:py-10 lg:py-12">
+```
+
+### 2. **标题区域改进**
+
+**当前问题：**
+- 标题区域仅 `mb-6` (24px) 间距
+- 标题字号偏小 `text-3xl`
+
+**改进方案：**
+```tsx
+// 之前
+<div className="mb-6">
+  <h1 className="text-3xl font-bold">CC Projects</h1>
+  <p className="mt-1 text-sm">Browse your Claude Code sessions</p>
+</div>
+
+// 之后
+<header className="mb-16">
+  <h1 className="text-4xl md:text-5xl font-bold tracking-tight">CC Projects</h1>
+  <p className="mt-3 text-base md:text-lg text-muted-foreground">
+    Browse and manage your Claude Code sessions
+  </p>
+</header>
+```
+
+### 3. **区块间距改进**
+
+**当前问题：**
+- 区块间仅使用 `space-y-8` (32px)
+- Active Sessions 与项目列表过于紧密
+
+**改进方案：**
+```tsx
+// 之前
+<div className="space-y-8">
+  <RunningClaudeSessions className="mb-8" />
+  <div className="pt-2">
+    <h2 className="text-lg font-semibold mb-6">All Projects</h2>
+
+// 之后
+<div className="space-y-16">
+  <RunningClaudeSessions className="mb-16" />
+  <section>
+    <h2 className="text-2xl font-semibold mb-8">All Projects</h2>
+```
+
+### 4. **卡片间距改进**
+
+**当前问题：**
+- 项目卡片间距 `gap-6` (24px) 稍显紧凑
+- 卡片内边距 `p-6` (24px) 不够宽松
+
+**改进方案：**
+```tsx
+// 之前
+<div className="grid gap-6">
+  <Card className="p-6">
+
+// 之后
+<div className="grid gap-8">
+  <Card className="p-8">
+```
+
+## 📊 视觉对比
+
+### 间距对比表
+
+| 元素 | 当前间距 | 建议间距 | 改进幅度 |
+|------|---------|---------|---------|
+| 页面内边距 | 24px | 48px (桌面) | +100% |
+| 标题到内容 | 24px | 64px | +167% |
+| 区块间距 | 32px | 64px | +100% |
+| 卡片间距 | 24px | 32px | +33% |
+| 卡片内边距 | 24px | 32px | +33% |
+
+## 🚀 实施步骤
+
+### 第一步：更新全局间距变量
+```css
+/* 在 globals.css 中添加 */
+:root {
+  --spacing-page: 48px;
+  --spacing-section: 64px;
+  --spacing-component: 32px;
+  --spacing-element: 16px;
+}
+```
+
+### 第二步：创建响应式间距工具类
+```tsx
+// utils/spacing.ts
+export const spacingClasses = {
+  page: "px-4 md:px-8 lg:px-12 py-6 md:py-10 lg:py-12",
+  section: "mb-16",
+  component: "p-8",
+  grid: "gap-8"
+};
+```
+
+### 第三步：逐步应用到组件
+1. 先更新 App.tsx 中的 projects 视图
+2. 更新 RunningClaudeSessions 组件
+3. 更新 ProjectList 组件
+4. 测试响应式效果
+
+## 💡 额外建议
+
+### 1. **添加视觉分隔**
+```tsx
+// 使用更明显的分隔线
+<div className="border-t-2 border-border/50 pt-16">
+```
+
+### 2. **增强卡片层次**
+```tsx
+// 活跃会话使用特殊样式
+<Card className="p-8 border-2 border-green-200/50 bg-green-50/30">
+```
+
+### 3. **改进空状态**
+```tsx
+// 当没有项目时，提供更好的视觉引导
+<div className="py-24 text-center">
+  <EmptyStateIcon className="mx-auto h-16 w-16 mb-6" />
+  <h3 className="text-lg font-medium mb-2">No projects yet</h3>
+  <p className="text-muted-foreground mb-8">
+    Start a new Claude Code session to create your first project
+  </p>
+  <Button size="lg">Create New Session</Button>
+</div>
+```
+
+## 🎨 设计原则总结
+
+1. **充足的留白**：宁可多留白，不要太拥挤
+2. **清晰的层次**：通过间距大小区分内容重要性
+3. **一致的节奏**：使用8px网格保持视觉节奏
+4. **响应式适配**：不同屏幕使用不同间距
+5. **功能分组**：相关内容靠近，无关内容远离
+
+## 📈 预期效果
+
+实施这些改进后，页面将：
+- ✅ 更加通透舒适，减少视觉压力
+- ✅ 信息层次更加清晰
+- ✅ 提升专业感和品质感
+- ✅ 改善用户浏览体验
+- ✅ 符合现代UI设计趋势

+# Usage Dashboard 布局改进建议
+
+## 📊 现状分析
+
+### 存在的问题：
+1. **视觉层次不明确** - 所有指标卡片大小相同，缺乏主次
+2. **数据展示单调** - 纯文字展示，缺乏可视化元素
+3. **信息密度过高** - 间距较小，视觉压力大
+4. **交互性不足** - 缺少时间筛选、数据导出等功能
+5. **响应式适配不足** - 移动端体验需要优化
+
+## 🎯 改进方案
+
+### 1. 视觉层次重构
+
+```tsx
+// ❌ 当前：所有卡片相同权重
+<div className="grid grid-cols-4 gap-4">
+  <Card>Total Cost</Card>
+  <Card>Sessions</Card>
+  <Card>Tokens</Card>
+  <Card>Avg Cost</Card>
+</div>
+
+// ✅ 改进：主要指标突出显示
+<div className="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-6">
+  <Card className="lg:col-span-2 p-8 bg-gradient-to-br from-red-50 to-orange-50">
+    {/* Total Cost 作为主要指标，占据两列 */}
+  </Card>
+  <Card className="p-8">{/* 次要指标 */}</Card>
+  <Card className="p-8">{/* 次要指标 */}</Card>
+</div>
+```
+
+### 2. 数据可视化增强
+
+#### Token Breakdown 改进
+```tsx
+// ❌ 当前：纯文字列表
+Input Tokens: 204.1K
+Output Tokens: 2.30M
+Cache Write: 45.10M
+Cache Read: 891.17M
+
+// ✅ 改进：使用进度条可视化
+<div className="space-y-4">
+  <div>
+    <div className="flex justify-between mb-2">
+      <span>Cache Read</span>
+      <span>891.17M (94.9%)</span>
+    </div>
+    <div className="h-3 bg-muted rounded-full">
+      <div className="h-full bg-green-500 rounded-full" style={{width: '94.9%'}} />
+    </div>
+  </div>
+  {/* 其他 tokens... */}
+</div>
+```
+
+### 3. 间距优化（8px网格系统）
+
+| 元素 | 当前间距 | 建议间距 | 说明 |
+|------|---------|---------|------|
+| 页面内边距 | p-6 | px-12 py-10 | 增加呼吸感 |
+| 卡片间距 | gap-4 | gap-6/gap-8 | 明确分组 |
+| 卡片内边距 | p-4 | p-8 | 内容更宽松 |
+| 区块间距 | mb-6 | mb-12 | 清晰分隔 |
+
+### 4. 颜色系统优化
+
+```css
+/* 语义化颜色方案 */
+--color-cost: red/orange (警示费用)
+--color-usage: blue (使用量信息)
+--color-performance: green (性能/效率)
+--color-neutral: gray (次要信息)
+
+/* 应用示例 */
+- Total Cost 卡片：红色渐变背景
+- Sessions：蓝色图标
+- 效率提升：绿色趋势箭头
+```
+
+### 5. 响应式断点设计
+
+```tsx
+// 移动优先的响应式网格
+<div className="grid 
+  grid-cols-1           // 移动端：单列
+  sm:grid-cols-2        // 平板：双列
+  lg:grid-cols-4        // 桌面：四列
+  gap-6"
+>
+```
+
+### 6. 交互功能增强
+
+#### 新增功能栏
+```tsx
+<div className="flex items-center gap-3">
+  {/* 时间范围选择 */}
+  <Button variant="outline">
+    <Calendar className="h-4 w-4 mr-2" />
+    Last 30 Days
+  </Button>
+  
+  {/* 数据刷新 */}
+  <Button variant="outline">
+    <RefreshCw className="h-4 w-4 mr-2" />
+    Refresh
+  </Button>
+  
+  {/* 数据导出 */}
+  <Button variant="outline">
+    <Download className="h-4 w-4 mr-2" />
+    Export
+  </Button>
+</div>
+```
+
+### 7. 卡片交互效果
+
+```css
+/* 悬停效果 */
+.card {
+  transition: all 0.2s ease;
+  cursor: pointer;
+}
+
+.card:hover {
+  transform: translateY(-2px);
+  box-shadow: 0 8px 16px rgba(0,0,0,0.1);
+  background-color: var(--muted-hover);
+}
+```
+
+### 8. 空状态设计
+
+```tsx
+// 当没有数据时的友好提示
+{data.length === 0 && (
+  <div className="text-center py-16">
+    <BarChart3 className="h-16 w-16 mx-auto text-muted-foreground/50 mb-4" />
+    <h3 className="text-lg font-medium mb-2">No usage data yet</h3>
+    <p className="text-muted-foreground">
+      Start using Claude Code to see your usage statistics
+    </p>
+  </div>
+)}
+```
+
+## 📐 设计规范总结
+
+### 间距规范

+- **卡片间距**: 24-32px
+- **内部padding**: 32px
+- **区块分隔**: 48-64px
+
