Rendering fields with their titles, theming CCK nodes?

I would like to print field titles, so each node is displayed like this:

field title 1:
field value 1

field title 2:
field value 2

field title 3:
field value 3

But instead I get:

field value 1
field value 2
field value 3

I have tried to figure out how, but this doesn't seem to be easy. I think what I'm trying to do is not so strange. In fact, IIRC this is how flexinode rendered nodes.

I wondering if you plan to add some kind of options to alter the way CCK nodes are rendered.

...or now, what's the best approach to add titles to field? Maybe adding a per content type option so field modules know if they had to include the field label when field_invoke(view) is called?

PS: This is looking like a feature request.
