Hmm, seeing this part of the interface brings back memories of working in Bryce. I really do need to take time to get back and play in it
Though the interface can be a bit confusing at times, Kai was an artistic genius.
You should never have stoped!
Yes, there are folks who find the interface condusing (not professional). Look at it as an adventure game, click on everything and be surprised at what happens. Once you know your way, the UI is easier and more fun to use than a “professional” one. There are exceptions, though. Some tools are burried a bit deep and going to them repeatedly gets a bit tedious. But on the whole, Kai made a great interface - still the greatest for an artist, but probably less so for a scientist.
