+# Feature Upgrade: History UI Overhaul
+
+**Context:**
+We are polishing the "Sidebar" component of the "LiteRequest" application.
+**Goal:** Improve the information density of the History list and add management features (Delete/Clear All).
+
+## 1. UI/UX Changes
+
+### 1.1 History Item Layout (Sidebar.vue)
+* **Current State:** Shows Method, URL, and Timestamp.
+* **New Layout:**
+    * **Remove:** Completely remove the Date/Time display to save space.
+    * **Flex Row:** The item should be a flex container (`flex items-center justify-between`).
+    * **Left Side (Info):**
+        * **Method Badge:** (Existing) e.g., "GET".
+        * **Status Badge (New):** Add a badge immediately after the Method.
+            * *Content:* The HTTP Status Code (e.g., 200, 404, 500).
+            * *Style:* Small, pill-shaped, lighter opacity background.
+            * *Color Logic:*
+                * 2xx: Text Green / Bg Green-500/20
+                * 3xx: Text Blue / Bg Blue-500/20
+                * 4xx: Text Orange / Bg Orange-500/20
+                * 5xx: Text Red / Bg Red-500/20
+        * **URL:** Truncate text if it's too long (`truncate` class).
+    * **Right Side (Actions):**
+        * **Delete Button (New):** A small "Trash" icon (`Trash2` from lucide-vue-next).
+        * *Behavior:* Visible on hover (group-hover) or always visible with low opacity.
+        * *Interaction:* Clicking this **must not** trigger the "Load Request" action of the list item (use `.stop` modifier).
+
+### 1.2 "Clear All" Functionality
+* **Location:** Add a "Clear" or "Trash" icon button in the **Header** of the Sidebar (next to the "History" tab label or the "LiteRequest" title).
+* **Style:** Subtle button, turns red on hover.
+* **Tooltip (Optional):** "Clear All History".
+
+## 2. Logic & State Management
+
+### 2.1 Store Updates (`stores/requestStore.ts`)
+* Add two new actions:
+    1.  `deleteHistoryItem(id: string)`: Removes a specific item from the `history` array by ID.
+    2.  `clearHistory()`: Empties the `history` array completely.
+* **Persistence:** Ensure `localStorage` is updated immediately after these actions.
+
+## 3. Implementation Details
+
+### A. Sidebar Component (`Sidebar.vue`)
+* **Status Badge Implementation:**
+    * Create a helper function `getStatusColor(code)` inside the component to return the correct Tailwind classes.
+* **Event Handling:**
+    * `<button @click.stop="store.deleteHistoryItem(item.id)">`
+    * The `.stop` modifier is critical to prevent opening the request while trying to delete it.
+
+### B. Icons
+* Import `Trash2` (for single item) and `Trash` (for clear all) from `lucide-vue-next`.
+
+## 4. Implementation Steps for AI
+
+Please generate the code updates in the following order:
+
+1.  **Store:** Add the `deleteHistoryItem` and `clearHistory` actions to `requestStore.ts`.
+2.  **Sidebar (Script):** Update the `<script setup>` to include the new icons and the status color helper function.
+3.  **Sidebar (Template):**
+    * Show the updated **Header** section (with "Clear All" button).
+    * Show the updated **History List Item** structure (Method + Status + URL + Delete Button).
+
+---
+**Instruction to AI:**
+Generate the code to apply these UI improvements and functional additions to the History module.
