I can see the current implementation is messy and broken. The message display is scattered, emoji reactions aren't properly integrated, and it doesn't look or function like WhatsApp at all. Let me explore the codebase first to understand what's there, then rebuild this properly with a clean WhatsApp-like interface.

Let me read the message-related components to understand the current structure:

Let me read more of the messages component to see how messages are rendered:

Let me check the CSS to understand the styling:

Now I understand the issue. The current implementation has proper code but the screenshot shows broken UI. Let me use EnterPlanMode to develop a comprehensive plan to rebuild this as a clean, properly working WhatsApp clone.

Now let me read more of the messages component to see the message input section:

Now let me create a comprehensive plan. Let me write it to the plan file:

Now let me call ExitPlanMode to let the user review the plan:

Now let me start implementing the rebuild. First, let me read the full messages component to understand the current structure and identify all issues:

Let me continue reading the messages component to see the JSX rendering:

I found the issue. The reply preview section (lines 846-890) references msg which doesn't exist in that scope - it should use replyingTo. Let me also check the CSS file to understand the styling issues:

Let me continue reading the CSS to see the message-bubble-sent and reaction styles:

Now I have a clear understanding of the issues. Let me fix the critical JSX error first - the reply preview section is referencing msg instead of replyingTo. I'll fix this:

Good! Now let me fix the remaining message input structure. Let me read that section first:

Now let me look at the message rendering section more carefully and improve it with proper message grouping and cleaner styling. Let me read the whole messages rendering area:

Now let me improve the message rendering to fix the reactions container positioning and message display. The reactions are showing outside/above messages due to absolute positioning issues. Let me fix this:

Good! Now let me improve the CSS to fix the reactions container positioning and ensure proper spacing. Let me update the CSS:

Now let me improve the mobile message display to match the desktop version with proper reactions and cleaner styling:

Now let me update the mobile message input to properly show the reply preview like the desktop version. Let me read that section first:

Let me check what's before that to see the full mobile input section:

Now let me update the mobile message input container to include the reply preview:

Now let me improve the conversation list styling to make it cleaner and more WhatsApp-like. Let me first read the conversation list section:

Good. The conversation list already looks decent. Now let me improve the renderMessageStatus function to make status indicators cleaner. Let me find it:

Good, the renderMessageStatus function looks clean. Now let me check how the message text styling works and ensure proper word breaks and spacing. Let me update the message textarea styling to be more responsive:

Now let me check the preview to see the current state. Let me create a console.log to track what's happening with the messages:

Good. Now let me make sure the input field classes are properly applied. Let me check if the message-textarea input styling is correctly applied:

Perfect. Now let me verify the main desktop display looks clean. Let me check if we need to handle the message bubble text styling better to ensure proper word wrapping:

Perfect. Now let me verify that the context menu on long press is working properly. Let me add a debug log to understand the flow better. Actually, let me first make sure the message input is properly bound to functions. Let me check the handleReactToMessage and other handlers:

Great! The handlers are all there. Now let me make one final improvement - let me ensure the message bubbles have proper focus states for accessibility and make sure the deleted messages are styled correctly. Let me also make the context menu more accessible:

Now let me make sure the message text in bubbles uses proper styling and ensure deleted messages look more professional:

Now let me verify the overall layout is correct by checking the main render section one more time to ensure everything connects properly. Let me add proper aria labels for accessibility on interactive elements:

Now let me add the type attribute to the send button as well:

Perfect. Now let me do a final summary of all the improvements I've made and verify the build is ready. Let me check if there are any remaining syntax errors by reviewing the key areas:

Now let me fix the mobile send button as well:

Excellent! Now let me verify the styling by checking that the message bubbles are properly aligned. Let me also ensure the spacing between messages is consistent. Let me update the spacing class to use a better margin:

Perfect. Now let me create a comprehensive summary document of all the changes made and verify everything is working. Let me check the main message rendering section one more time to ensure there are no issues:

Great! The structure looks good. Now let me verify the overall layout flow one last time. Let me check for any remaining debug logs that might have been left:

I see there are some debug logs, but they're helpful for understanding the fetch flow, so I'll leave those. Now let me create a final summary of all the changes and improvements made. Let me write a summary file:

Let me create the summary in a different location:

Now let me verify everything is properly set up by doing a final check of the key components. Let me make sure the message context menu component doesn't have any issues:

Good! The context menu looks well-structured. Now let me ensure proper export and overall structure. Let me check if we have all the necessary styling in place by verifying the input field has proper focus behavior:

Now let me verify that we have a complete and clean implementation. Let me check the package.json to ensure all dependencies are in place:

All the necessary dependencies are in place (framer-motion, lucide-react, etc.). Now let me create a final verification to ensure there are no syntax errors in the main file:

The component structure looks good. Now let me verify the closing braces are proper. Let me check the end of the file:

The file structure is complete and properly closed. Now let me do a final check to make sure all the improvements I made are properly integrated. Let me create a comprehensive list of what was accomplished:
