Introduction

To create extensions that improve functionality and bring joy to users, it's important to focus on user-centered design, thoughtful layout strategies, and effective use of color and typography. Let's explore how you can successfully integrate your extensions with the Simple experience. If you plan to publish your App on the Marketplace, please review our Marketplace App Guidelines for the Design and Usability section.

Design principles

Your UI should adhere to the following key principles:

• Customer-focused: The app's purpose and value should be defined around the needs of the users. It should solve a unique problem for them.
• Simplicity: Your app should be simple to use and not require extensive learning to get started. It should complement the visual abstraction of code, not complicate it.
• Design: Use consistent design elements like color, typography, and button styles throughout your App. This improves the user experience and makes your app easier to navigate.
