In the Projucer when we rename a file that is paired (.h and .cpp with the same name) it proposes to rename the other file, but without changing the header name included in the cpp.
In a perfect world it would update all includes of the project, but at least the one in the .cpp renamed would be a great start.
The standard use cases I’m facing is to create files with projucer, and doing a mistake in the name that need to be renamed. Or changing the name later because it was poorly chosen.
Can you add this for next update please ?
