It would be very helpful if, during pre-compilation, the loadLayout method - does NOT find the layout file in the resources folder - is NOT declared in the hidden section in the Main module with the "File<N>=" tag write an error message and DO NOT allow the program to be compiled.

A tool/functionality would be useful that: starts with a method and lists all the methods that use that method, then recursively lists the methods above it until reaching the input methods (e.g., main or user event input).
