🎯 Why Customize a Canvas App?

Customizing your Canvas App ensures:

🖌️ UI Enhancements & Custom Styling

Power Apps provides multiple ways to style and enhance the user interface to improve usability and branding.

🎨 Theme Customization

Use prebuilt themes or define custom colors and fonts.
Set a consistent design across screens for a professional look.

🖼️ Working with Screens & Controls

Each screen in Power Apps plays a specific role. Here’s how to structure and customize them effectively:

📌 Key Screen Types:

✅ Home Screen: Welcome users and provide easy navigation.
✅ Browse Screen: Display a list of records with filtering and sorting options.

✔ Galleries & Data Tables – Customize layouts, sorting, and conditional formatting.
✔ Forms & Dropdowns – Set up required fields, default selections, and validation rules.

A well-structured navigation model improves the user flow and ensures an intuitive experience.

Use the Navigate() function to move between screens:

✔ Can be combined with logic for conditional navigation.

Create a custom sidebar or header menu for consistent navigation:
✅ Add a gallery control with navigation links.
✅ Use icons instead of text for a cleaner look.
✅ Ensure it’s available on all screens for easy access.

Patch(DataSource, Defaults(DataSource), {Title: "New Record", Status: "Active"})

✔ LookUp() – Fetch specific records from a data source.

LookUp(Employees, EmployeeID = 1001, Name)

✔ Filter() & Search() – Enable dynamic data filtering.

Filter(Products, Category = "Electronics")

✔ Set() – Store variables for user actions.

Set(currentUser, User().FullName)
