Awesome! I like it. Do you have another version that might be more up to date? I would love to try it out. Yes, It reminds me of old school doom editor by here there is no need for computing BSP Trees though Duke Nuck'em used beck to front rendering. Love to see where this goes in the future and you might be ahead of this now that I look at it. So yes, I am very interested in any up-to-date information.
