What is the usefulness of the PHPCG comparison tool?
In some specific cases it may be useful to customize some files of the Bootstrap Admin Dashboard - so modify the code created by the CRUD Generator.
This is especially true for PHP classes, TWIG templates and forms.
If you have modified the source code, and regenerate the files using the CRUD Generator, for example following a modification of your database or simply to change your settings, the files will be overwritten and you will lose your custom code.
To avoid this problem PHP CRUD Generator offers an efficient tool, called the "File Comparison Tool".
