How to theme title field Normally when I theme a field, I use a template suggestion in format field--fieldname--contenttype.  However, it doesn't seem to be possible to do this with the node title.  I've tried both of the following template suggestions:

field--title--contenttype.tpl.php
field--field-title--contenttype.tpl.php


Neither of them work (I've cleared caches).  The title isn't technically a field, since it's more like a property on the node object, so that may be the problem?

Is there any way to theme the title field?  It feels like I'm missing something simple.

N.b. I'm using panels and have dropped the node title pane into the panel but need to theme it differently.
You could use the Title module to convert your title to a proper field. Following that, your template file should work.
