I know about that Michael! In fact that's what I used to programmatically set the active layer I was talking about. The thing is that MoI doesn't have the concept of completely hiding a specific style. I mean if you hide objects that have the orange style for example, and then generate a new object with that style, the last object would be visible. It doesn't align with the concept of a layer where everything in a layer can only be hidden or not.
Take for example Photoshop, where you're not allowed to draw on a hidden layer. That's what I attempted to do with scripting, but this thing was a show-stopper.
