You may edit the contents of the class using this form. Commas, newlines and double quotes (") must be handled delicately. You may include commas and newlines by enclosing the values in double-quotes ("). Double quotes themselves must be quoted by doubling ("").
Multilink properties have their multiple values colon (":") separated (... ,"one:two:three", ...)
Remove entries by deleting their line. Add new entries by appending them to the table - put an X in the id column.
