While it is nice to have the option to separately activate/deactivate optics and zoom, it would be nice to have an option for your view to automatically zoom in whenever you raise your sights, and possibly also automatically zoom out whenever you lower your sights.
In the end, whenever I raise my sights I also zoom in so I can hit my target, but that generally requires too many key presses.
This cannot be achieved with overlapping key bindings, as you might already be zoomed in when you raise your sights, in which case toggle zoom will zoom you out.
