Creating application views currently takes place in a "what-you-see-is-what-you-get" mode. In other words, you create a view and see that view. To edit the view’s parameters, you must view the view in order to modify its configuration.
This approach is a great solution in many cases because it eliminates the need to navigate through a large configuration tree to find the specific location where a particular property can be set or changed. Instead, you can navigate to the problematic location in the application and display the subconfiguration there. However, this approach reaches its limits if you’ve made an error that prevents a specific view from being displayed at all. In this case, the only option so far has been to export the layout to the development environment and edit the XML there.
This can happen quite easily if you make a mistake in an executability rule that causes a button not to be displayed at all or to no longer be displayed.
Improvement
A Layout Editor view in the Development area where you can view, edit, and create the configuration of all the application’s layouts without having to display the corresponding parent view at all (or switch the application to design mode).
Test
Navigate to the Administration > Development > Layout Editor view, and edit and save a legacy and a template layout.
