I think the old SE could be improved functionally though. Like if you try to mark one stone as dead it just decides all stones of that colour should be dead. Trying other things like shift clicking to mark individual points (I think it’s shift?) end up just sticking and moving the mouse marks a trail of points etc.
I think you could improve its functionality instead of its accuracy, as people mentioned in the other thread, you more or less have to seal boundaries in analysis mode first before it’s any use. If people are going to do that anyway, why not make it a bit easier for them.
