Is there any chance the icons for replica and duplicate can be adjusted. its almost impossible to tell them apart, since they are both TINY boxes, with the only difference being dotted vs solid lines, which is far too subtle to make out. I guess everyone at DT has great eyesight, but even with 20/20 vision I literally cannot tell them apart without peering up-close to my (expensive, high quality) monitor.
(screen shot attached if you want to peer at them and figure out which is which…)
