I'm currently running v3.5.1 and are wondering the same thing. I would much prefer if it printed multiple objects like this:
LAYER 1: 1, 2, 3, 4
LAYER 2: 4, 3, 2, 1
LAYER 3: 1, 2, 3, 4
LAYER 4: 4, 3, 2, 1
etc.
The way it currently works, when there are lots of little objects on the build plate, there is a massive travel at the end of each layer, which is not very efficient.
