Zoom down steps too big

cmd - used to take you not straight to 50%. I think this jump is way too big. If you take a regular website, shrink it 50%, it is no readable and it’s hard to work with it. At 80% it is readable and you can work with it. More granular steps would be more effective I think. Maybe, decrease by 20%. Now I have to go the box to change the percent - too much work. It needs to have keyboard only support as well since we can spend all day in Axure.
Thanks!
