annoyed with leaving indentations of a vice in my saws bars when servicing, bench testing saws, sharpening chains and annoyed with trying to balance saw/ old scraps of wood and tighten the vise I threw together a "jig"that drops in to vice. Used scraps of wood 1x, a scrap of 1/4" plywood and 5 mins of my time, its worked better than expected for what I needed and cost nothing. I apologize if something like this was posted before, and I'm sure there are better ways.
