Actually, I don't know why you are supposed to use all those boxes. IMHO, it 
should suffice to create the scroll view with the table view. You may want to 
have a look at Burn.app, for instance. The main window (ProjectWindow.[hm]) 
does exactly what you try to do (except that I use a customized outline view, 
but that is not so different). GNUMail.app also sets up table/outline views 
manually.

I agree with you here. Having a tool such as Gorm is really nice, but one 
should know what happens behind the scenes. In particular when it comes to 
doing stuff that exceeds Gorm's (current) limitations, e.g. when you need to 
set up a custom view. Then you must fall back to doing things manually.
Nevertheless, Gorm is great and once you've figured out how to do it the hard 
way you should redo things the soft way :-)
BTW, how about naming your app simply Charmap(.app). We all know that we are 
on GNUstep ;-)

Cheers,
Andreas
