Level design prototyping in Blender

I’ve just came across this tool for Unity which is really nice: https://www.youtube.com/watch?v=Kjqx6cKUepc

I wonder if there are plugins for Blender that allow the interface of level prototyping to be easier, as well increase the efficiency of box-modeling. But, most importantly, easy UV-unwrapping.

Hello
well, sometimes the " new tool" looks “much cooler” than Blender, but this one works almost exactly like Blender?..
Keep blending!
