"How do these print in reports, do they appear in any of the standard reports for eithe descendants or ancestors." I don't know since I have not yet had a reason to use these relationships. mk
"Do multiple marriages show on any of the charts?" What "charts" do you mean? If you mean a Family Group Sheet, it works the same as in UFT: print a FGS report for one marriage and other marriages are mentioned on it. Then print a FGS for the next marriage and the first marriage will be mentioned, etc.
"Do half sibling relationships appear in any reports?" Which reports do you ask about? The answer is probably yes. Otherwise, why have the relationship tags in the first place? Again, I have no step-children entered in my databases so I cannot check beyond the TMG manual.
Perhaps you did not know. TMG and UFT were almost neck-and-neck in features and methods until UFT was abandoned by its corporate owners. TMG led the pack then, and still is at the head of the line of all Windows Genealogical programs.
Experienced TMG users tell us that TMG can be customized to do just about anything the user wants. I have been learning and using and teaching TMG for about a year. I would never go back to any other program.
