Ok, I've got much further and now have questions.

I have a GtkTreeView, and two buttons - "Add" and "Remove".
These act as you'd expect. The user can edit the header name 
by double clicking on it - the editing occurs inside the 
GtkTreeView.

If the user enters a value that is inappropriate for a header 
name (eg. it contains a " ", or a trailing ":"), should I 
reject the change - revert the field to its previous contents? 
I can't think of another way, but this doesn't provide useful 
feedback to the user - they'll be left wondering why their 
change isn't working.

Also, should I have some sort of explanatory text field - none 
of the other tabs seem to have them, but this tab doesn't make 
much sense without some explanation. I tried to do it with 
a tooltip, however that just worked out silly.

(I have it storing into / retrieving from GConf - yay)

When they click the "Add" button, should it jump them into 
editing the text field in the list? Can anyone hint how to 
achieve that, if it's desirable?

Cheers for any help / suggestions
