Hi Tristan.

Defining the model data in the GUI is tempting, but I doubt if it is
entirely appropiate or useful. The interface is likely to become
complicated, for example permitting conditional attributes... 

_Not_ having all possibilities available in the GUI is, IMHO,
counter-productive, as reliance on a GUI would mean less frequent
'manual' use...

   Here is my own personal opinion on the matter...

Treeviews are designed for optimization, you can display a
dataset of 100,000 rows in a treeview and you'll only render
the visible rows - this is the excelent value of the GtkTreeView.

Over time, treeviews have been abused, people use treeviews
to display a static list of choices for example - a job much
better suited for some simple canvas implementation, a dropdown
menu, combo box or such - why do I call this abuse ? because
it shouldnt take someone the effort of writing an entire treeview
code just to display a couple of options.

So, in the terms of what I think are valid use cases of a treeview,
where a treeview is not overkill for the task at hand, the model 
data is invariably dynamic, nothing that could be defined in a
GUI designer.

So I would opt to sooner add support for canvases etc in glade
for those cases where people need simple hardcoded lists/choices,
and leave dynamic model data to the programmer to generate.

Maybe thats a drastic opinion ;-)
