So that the host application can lay out the plugin widgets cleanly.[1]

After reading your comments, I suppose I was thinking of "internal" GUI's 
where the widgets are layed out by the host application.  For example, if 
I was writing an application, I couldn't use zynadd's UI because it's way 
to large (both the overall size and the size of the widgets).

I (personally) really don't like having plugin windows flying all over the 
place.  I think they should be layed out in the host application.  (And I 
also think they should be widget-toolkit agnostic -- 
Qt/GTK/FLTK/whatever.)

Thanks,
Gabriel

p.s. I'm still digesting the rest of your post.

[1] After more thought, it would probably be best to drop the 600 width.
