Thanks for the feedback.
@Heinrich Yes, that would be nice. I was hoping in the future, I could
allow for the user to set some kind of precision value. That would make
sure we have a fixed number of digits after the decimal. May be for now, I
could "fix" that value and make it align.
@Tony Yes, I do have a piece of code commented out where I attempted to
make it generic but did not pursue that option. Your suggestion is very
valid and I am hoping to get there.
