Add modal configuration, date formatting, structured data and permissions.

Wording seems a little off "to _not_ form"... "to avoid forming" might make more sense? Also: "Note: All [...]" or "Note _that_ all fields [...]" could make it easier to read?

"Note: If this feature is used, all fields must be filled out; otherwise, any value entered will be ignored to avoid forming incomplete structured data tags."

...  Mumble...
