Sure. I am mainly SubD modeler but lately I do more and more cad works. When I work layer colors are important in my workflow because after many hours of working I`m not seeing very well.
So I colorize things. Red color is means for me it`s latest version of object. White color for me are boolean cutters. Other colors means helpers and temp meshes. When I started to do bigger project in MoI I`ve found that I need those coloring feature. I don`t know is it good for MoI or not.
I only say that for me foders and colors are helpful. I feel that notes would be also helpful when you would like to repeat operation once again and you don`t remember past values.



edit: please note also that Modo layers are written bolder text when on layer is present some geometry. If layer are written with thin text (like in my example above) it means that those layers are empty. In MoI there is no such a problem because without geometry is no object :) - no empty layers (what is not bad).
