Subdividing of rooms

[NinoMishler]

I'd love to see an easy way to subdivide rooms. The ceiling lights in the center of a large room are often too dim. By subdividing the room into smaller areas, each with their own center light, larger rooms would not suffer.

You can draw a room point by point and magnetism will help you to find wall corners.
You could also not rely on automatic ceiling lights and place your own source lights.
