I dream of a tool to apply a color scheme on views and/or layouts, based on properties of objects (room height, finishes, fire rating, etc...).
It would be a great improvement, time saving and ability to control parameters of objects in a visual way.
I think this can be achieved with a (heavy?) scripting in GDL on the zone stamp... but It probably would require a lot of scripting depending on how many variables you want to control.
Yes, it would be very useful to create visual legenda.
