Currently it seems the visibility is only associated with the workspace, which is nice, but I suggest taking it a step further.
Wouldn't it be nice to have each CAM operations folder associated with the visibility selections of the respective components that are used in that operation?
It could be either a manual selection, meaning as the user toggles what they want visible in that setup it remembers, or perhaps it could be related to the models and fixtures selected in the setup itself.
As my parts and designs get more complex with various versions of components, fixtures ect, it gets to be a hassle toggling visibility of the components that relate to each cam setup. I think as you are working in a setup, it should remember what components were visible and when you toggle each folders radio button only those components should be visible and all the others hidden. It would make things much less confusing and save a bunch of time.
My two cents,
