"Check all checkboxes" option for ACL rules in Ratel.

[danielmai]

It's common to create groups that have read-only access to all the predicates. It'd be nice to be able to set the read-only permission to all the predicates via a checkbox that would automatically set the corresponding permission (read, modify, or write) for all the predicates. Today, you need to check each box one by one for each predicate.
