In my opinion, this is a far better idea for development than the one which started this topic.

For me, the ability to instantly transpose is just about the only virtue that Chordpro has. Unfortunately this is far outweighed by, what I perceive, as its shortcomings.

I'm not sure why you would want to change the terminology to 'grid' - we all know what a chord chart is and I see no practical reason to give an established thing a different name.
