Photolab3.3.3.60 Mac OS Mojave
My “picked, untagged, rejected” indicators show only when I hover over the image in Photolibrary or Customize view. In Full Screen mode, the selection is visible, but that may be because there is only the one image being displayed.
I seem to recall the red, green or nothing designations showing all the time in the filmstrip when I was in the Customize view in older versions of PL.
If I have to constantly search for my “picks”, it is a waste of my time. Using the filter to move through the categories is another time waster.
