New Feature: Many-to-many Relationships

A much-requested feature, dbdiagram now supports Many-to-many Relationships!

When drawing the many-to-many relationship, you no longer need to create an associative (join) table. Instead, just define it directly, such as:

Table books {
  id int [pk]
  ...
}

Table authors {
  id int [pk]
  ...
}

Ref books_authors: books.id <> authors.id // many-to-many
