Idea Summary
Change the way attributes are added to the modal to make it easier to maintain and write them.

Use Case
Sometimes we have to use the opening of modals and make some pre-configurations to the dialog through the Attributes field so that the modal behaves the way we need it to in some respects, while respecting the Apex structure. Here it's worth pointing out that the settings can be simple, such as the ‘closeOnEscape: false’ function to prevent the modal from being exited by the ESC key, or even more complex, such as creating a function for actions in it, but the field is limited to 255 characters, which prevents the settings from being viewed and edited satisfactorily.

Preferred Solution (Optional)
Create a section to create all the attributes, linking them to the page via an alias or enlarging the field, as well as adding a window as the Javascript editor.
