Row lines -- try using the "Alternate Rows Background" in the Project: Colors inspector

Completed milestones -- there is no way to even mark a milestone completed; should there be?

The milestones' date & time visibility setting should be separate from the resources -- we know about that bug

group shading -- we should print that if it's shown. I'll file that bug.

critical path coloring -- we do have a "glow" you can turn on for critical path tasks; is there a reason you want to color the tasks themselves?
