just an utopie,
I thinks to modify blocky to made a Snap with three.js integration (as blocks)
the project would be directly coded in javascript, and would directly read with a web navigator, you could separate the gui in 2 windows if you work with 2 screen, make your project with power of javascript, but it's an utopie, but you can try my javascript's blocks in this project (in variable other cathegory) in this project, inside https://snap.berkeley.edu/project?user=gego51&project=textured%203d%20cube
