When offsetting lines in sketch mode, there should be the availability to offset multiple lines at once. Such as holding the control button to select multiple lines. I often have instances where I have to offset multiple lines that aren't connected to show in a 3D model where parts would be waterjet cut and be nicked in to have the option to be removed if necessary. It would save a lot of drafting time if you were able to select multiple lines, whether split or not, instead of having to offset one line at a time.
