Some times when making a Quick part up Or Programming the CAM for a part . I'm jumping between parts editing sketches, features and Operations. I forget to activate the component or operation in CAM and it ends up taking longer because sketches don't show up for the parts they are suppose to be for. There just isn't an easy way at a glance to see what part or cam is activated, I find my self hovering over all my parts in large assemblies trying to see were I screwed up and were I was actually editing .
A Simple improvement could be like not to auto hide the dot that you select when you activate a part that way it will always be visible at a quick glance.
Best regards,
