How can I add Help text to the Title in D7?
Perhaps adding an 'edit' button similar to the other normal fields.
Ideally the solution integrates with Label Help.
'title' on a node is not a field, but a property, you can convert it into a field (with all it's goodness) with https://www.drupal.org/project/title .
