LMArena | Floating Copy Buttons

Adds persistent, always-visible copy buttons with native Drag-and-Drop support for code blocks and chat messages.

Why You Need This

Native copy buttons disappear when you scroll:

• Code blocks: Button fixed at top - invisible when viewing the middle or bottom
• User messages: Button appears on hover, vertically centered to the left - disappears when scrolled out of view
  
• AI messages: Button buried in bottom action bar - requires scrolling to message end

This script keeps copy buttons accessible wherever you are on the page.

What It Does

Code Blocks

• Interactive Copy Code Column: A transparent strip on the right edge of every code block
• Enhanced Header Button: Custom drag-enabled copy button replaces the native one

Chat Messages

• Floating Buttons: Smart-positioned buttons beside AI (right) and user (left) messages
• Scroll-Tracking: Buttons follow messages as you scroll through long conversations
• Adaptive Layout: Automatically adjusts to available screen space

Dual Action Workflow

• Click: Instantly copies to clipboard
• Drag: Hold and drag any button to drop text directly into your IDE, notes, or anywhere
  • Bonus: Chat messages automatically convert to clean Markdown when dragged!
• No Hold Delay: Drag starts immediately on mouse movement
