I'll create a notes app that looks like a yellow legal pad with tabs for switching between different contexts.

This notes app features:

1. A yellow legal pad design with blue horizontal lines and a red margin line
2. Tabs to switch between different contexts (Personal, Work, Ideas)
3. A realistic notepad appearance with proper styling
4. Ability to edit notes in each context
5. A save button (currently just visual, but could be connected to storage)

The app is fully responsive and maintains the legal pad appearance across different screen sizes. You can easily add more contexts or features like:

• Local storage to persist notes
• Rich text formatting
• Adding/removing tabs
• Sharing functionality

To use this app, just copy the code into your Next.js project. The main component is NotePad which handles all the note-taking functionality.

I'll redesign the notes app with an Apple-inspired premium look, using their color palette and design principles.

I've redesigned the notes app with an Apple-inspired premium look:

Key Design Changes:

1. Color Palette:

   • Used Apple's signature light gray background (#F5F5F7)
   • Applied Apple's blue accent color (#007AFF) for interactive elements
   • Kept a subtle cream color for the notepad (#FFFEF0) that's more refined

2. UI Elements:

   • Added rounded corners and subtle shadows for a premium feel
   • Implemented Apple-style tab design with clean, minimal styling
   • Removed the red margin line for a cleaner look
   • Made the horizontal lines more subtle and professional

3. Typography:

   • Used Apple's text styling with appropriate font weights
   • Improved spacing and alignment for better readability

The app maintains all the same functionality but now has a premium, Apple-inspired aesthetic that's clean and precise without overdoing any design elements.
