    When I try to shift the edge, it moves a bit, then stops. If the most primitive user interface function already fails, then that means instant uninstall.

    but there needs to be where we can manually (as in a number pad) to put how many mm/inches to see how it actually looks like, instead of sliding it. If its in pro, I'll buy it.
