Harpster,
you are most welcome!
With irb you can tweak charts however it suits you. I feel that the charts are just a suggested road map of 'a' way to go. When I try to add too much information to small format irb charts, it makes them less readable for my purpose. As a bassist, I'm less concerned about if it's a ii,V,I change vs. just a V,I or the precise details of a turnaround than WHERE that key change went or what the heck is that mystery chord.
irb suits my purpose very well.
If the charts that I've shared are helpful, that's great.
