Hi Marco,

This is something I feel would be very helpful as the default behaviour.

While improving Sweet Home 3D's render engine results (user db4tech), 
lights is one of the areas I looked at, allowing size (for soft shadows) 
and intensity changes, previously lights had a small fixed size and 
intensity. One of my goals, to make it easier for artists, was to try 
and make sure lights intensity remained constant while size was 
adjusted. Certainly made light manipulation a lot easier and received 
very positive feedback.
