[I'm CC'ing `gnugo-devel' as some people there are interested in this functionality.]
Game tree view much like in Cgoban1 has been implemented in upstream CVS version of Quarry. It has the very same layout as in Cgoban1, but works much faster (noticeable on huge trees only.) Implementation is not yet finished, but is already useful. You can already click on a node in the view to switch to it. Additional planned features: * Collapsable nodes (right click to collapse/expand?) Machinery is already there, mostly it is GUI frontend lacking. * Automatic scrolling of the view to follow the current node (configurable.) * Show/hide the tree view from menu. * Maybe a way to narrow to a subtree (Emacs users will understand.) * Zooming of the view, i.e. adjusting stones' size (most likely delayed.) Known bugs: * With really huge trees there can be glitches in line drawing. This is an X problem, I'll need to find a workaround. I would like this new feature to be tested as much as possible. Let me know if you discover any problems. Ideas and suggestions are also welcome. Paul
