Goal of this tool/app is to help community in contributing to Godot's class documentation.
It is a useful tool for people willing to contribute, who prefer simple, intuitive GUI instead of editing xml file with text editor.
App loads all the classes data along with their properties from classes.xml, allows you to easily and comfortable edit that data, then saves your changes back to the file.
