Prevent a part from highlighting on hover if it is hidden
If you click on a part and deselect the eyeball the part is still highlighted in the render window via the selection color from the pallet. It is not until you click off of the part in the geometry browser does the part disappears in the render window. If you click on the eye ball without selecting the part first the part disappears immediately because the part was not selected, hence, no selection color to be shown.
Import some Geometry
Select the part you which to hide in the geometry panel
Left click on the eyeball to hide the geometry. The part is still shown via the selection color
Left click on another part and the part is now hidden.
