It would be really great if when you changed a field name, deleted a field - or changed a view parameter name - it searched all the code not just deluge field references.
For example, changing the field example to example_new would be flagged in this deluge code:
example="test";
but would not be flagged if was used in a URL built to call that form. For example
would not be flagged even though it is equally broken!
Just an idea.
