+### Message Content Features
+
+The application automatically enhances message content with interactive elements:
+
+#### Mention Badges
+User mentions in the format `@[Username]` are displayed as styled blue badges (similar to the Android Meshcore app), making it easier to identify who is being addressed in a conversation.
+
+**Example:** `@[MarWoj] test w Kielcach` displays with "MarWoj" as a blue badge.
+
+#### Clickable URLs
+URLs starting with `http://` or `https://` are automatically converted to clickable links that open in a new browser tab.
+
+**Example:** `https://example.com` becomes a clickable blue link.
+
+#### Image Previews
+URLs ending in `.jpg`, `.jpeg`, `.png`, `.gif`, or `.webp` are displayed as:
+- **Inline thumbnails** (max 300x200px on desktop, 200x150px on mobile)
+- **Click-to-expand** - Click any thumbnail to view the full-size image in a modal preview
+- **Lazy loading** - Images load only when needed for better performance
+- **Error handling** - Broken images show a placeholder
+
+**Example:** Sending `https://example.com/photo.jpg` shows a thumbnail of the image that can be clicked to view full-size.
+
+**Note:** All content enhancements work in both channel messages and Direct Messages (DM).
