+# UI Improvement: Resizable Panels & Copy Action
+
+**Context:**
+We are polishing the "Main Workspace" area of the LiteRequest application.
+**Goal:**
+1.  Add a **"Copy Body" button** to the Response Panel for quick access to the result.
+2.  Make the vertical split between the **Request Panel** (top) and **Response Panel** (bottom) resizable by the user.
+
+## 1. Feature: Response Copy Button
+
+### 1.1 UI Changes
+* **Location:** Inside the `ResponsePanel.vue`, in the **Meta Bar / Header** (the row displaying Status Code and Time), aligned to the right.
+* **Icon:** Use the `Clipboard` icon from `lucide-vue-next`.
+* **Interaction:**
+    * **Default:** Shows the `Clipboard` icon.
+    * **On Click:** Copies the content of the Response Body to the system clipboard.
+    * **Feedback:** After clicking, change the icon to `Check` (Checkmark) for 2 seconds to indicate success, then revert to `Clipboard`.
+* **Style:** Small, ghost-style button (transparent background, changing color on hover).
+
+### 1.2 Logic Implementation
+* Use the browser API: `navigator.clipboard.writeText(props.body)`.
+* Use a local ref `isCopied` (boolean) to handle the icon toggle state.
+* Use `setTimeout` to reset `isCopied` back to `false` after 2000ms.
+
+## 2. Feature: Resizable Split Pane
+
+### 2.1 UI Changes
+* **Location:** The parent component that contains `<RequestPanel />` and `<ResponsePanel />` (likely `App.vue` or `MainWorkspace.vue`).
+* **Visuals:** Insert a **Resizer Handle** (a thin horizontal bar) between the two panels.
+    * *Height:* 4px - 6px.
+    * *Color:* `bg-slate-800` (hover: `bg-indigo-500`).
+    * *Cursor:* `cursor-row-resize`.
+
+### 2.2 Logic Implementation
+* **State:** Use a `ref` for `topPanelHeight` (initially `50%` or `50vh`).
+* **Drag Logic:**
+    1.  **`onMouseDown`** (on the Resizer): Set a `isDragging` flag to true. Add `mousemove` and `mouseup` event listeners to the `window` (global).
+    2.  **`onMouseMove`** (on Window): Calculate the new percentage or pixel height based on `e.clientY` relative to the window height. Update `topPanelHeight`.
+    3.  **`onMouseUp`** (on Window): Set `isDragging` to false. Remove the window event listeners.
+* **Layout Application:**
+    * Apply `:style="{ height: topPanelHeight }"` to the **Request Panel** container.
+    * Apply `flex-1` (or calculated remaining height) to the **Response Panel** container.
+    * Ensure `min-height` is set (e.g., 200px) on both panels to prevent them from collapsing completely.
+
+## 3. Implementation Steps for AI
+
+Please generate the code updates in the following order:
+
+1.  **ResponsePanel.vue:**
+    * Update the template to include the Copy Button in the header.
+    * Add the script logic for `copyToClipboard`.
+2.  **Main Layout (App.vue or similar):**
+    * Refactor the template to wrap RequestPanel and ResponsePanel in the resizable structure.
+    * Implement the `useDraggable` logic (or manual event handlers) in `<script setup>`.
+    * Add the `<div class="resizer ...">` element styles.
+
+---
+**Instruction to AI:**
+Generate the specific code to add the copy functionality and the resizable split view logic.
