Thomthom's Model Info gives you certain amount of info about your model but not sure if it lists per item. AdamB's Goldilocks v2 indicates hi-poly object based on view. So if you have a hi-poly cup 20' from view it'll indicate it. Fredo has a Triangle count tool but I forget the name. I don't think there's something that does exactly what you want. But I could be wrong....

Thanks.

Yes, there is one with a visual history - Samuel Tallet visual_history But, in my experience, it requires some solid CPU...

Hi folks. You can also use the Move Tool after doing a carefull selection of the stile inside the component definition. Moving the selection will then automatically stretch all edges connected to it. However, if the window component is composed of subcomponents, this can become a bit tedious. Just ideas.
