Discovering a Hidden Dynamics 365 Customization Page and Leveraging PowerApps Samples
As a Dynamics 365 and Power Platform developer, I am always looking for tools, shortcuts, and resources that can simplify customization and development activities.

This page provides direct access to System Customization features and can be useful for administrators and developers who need to quickly navigate to customization settings without going through the standard application menus.
Why This Is Interesting

These pages can help:Quickly access entity customizations
Review solution components
Troubleshoot configuration issues
Validate customizations after deployments
Save time during development and testing activities
For experienced CRM developers, knowing these direct URLs can significantly improve productivity.
