I'm not sure that's right. While users certainly don't know about `frame-root-window' windows, the tree is otherwise readily apparent (since, for instance, resizing or deleting a window distinguishes +-+-+ +-+-+ |A|B| |A|B| +-|-+ and +---+ |C|D| |C|D| +-+-+ +-+-+ in an immediately obvious fashion). Why not store a configuration as a (resolution-independent) tree: subtree = window | tree ; tree = "(", horiz, subtree, split, { split }, ")" ; split = fraction, subtree ; horiz = nil | t ; (* t for C-x 3 *) fraction = ? float ? ; window = ? ... ? ; (* the hard part *) very much like (window-tree)?
