Fiori Doctor is a Chrome add-on developed by Krishna Kishor Kammaje that is a must-have tool for Fiori developers. This free tool allows developers to easily explore which UI5 controls were used in a Fiori or UI5 app. With just a click of a button, users can gain valuable insights into the UI5 controls used in their app, making it easier to understand and navigate the codebase.

One of the standout features of Fiori Doctor is the ability to shift+click to navigate to the UI5 explorer. This feature allows developers to quickly jump to the UI5 explorer and gain a deeper understanding of the UI5 controls being used in their app. This can be incredibly useful for troubleshooting and debugging purposes.

Please note that Fiori Doctor is not directly associated with SAP, and "Fiori" is a trademark of SAP. However, if you are a Fiori developer, this tool is a valuable addition to your toolkit. By providing insights into the UI5 controls used in your app, Fiori Doctor can help streamline your development process and enhance your productivity.
