More Conditioning Options
Exact match option as a more stringent condition versus the default find matching for more fine grained control over the condition.
Literal option to treat the pattern as a literal string. Makes it easier for simple conditions - don't have to worry about escaping special regex characters.
Negative (or Reverse) option. Make it easy to specify a condition that when matched will prevent the issue from being created.
