When you create a Module you will get an Action column which has only delete on it. It would be nice if there was an Edit as well.
I had one module with First Name, Last Name, E-Mail columns and the E-mail column was the link to edit. My user did not automatically realise that he had to click on the email address to change the record.
PS: I guess it would be nice if the module would also support Publish/Unpublish under acitons.
