New Style which enables you to quickly see what parts of your model need to yet to be assigned or which classification they have.
Maybe too late for it now but what I’d like to see is for “Layers” and Classifications to be merged into one feature. SketchUp “Layers” are already classes or tags you apply to objects, not drawing contexts as layers usually are. It seems redundant to both assign a class and a layer to an object, both saying git is a wall, or a piece of furniture.
Anyhow, I approve of the original idea here too.
