We’re unlikely to do a complete rework of the chord symbols features – one of the running jokes we have in the team is that at least one member must always be working on chord symbols, and has been since we embarked on working on them at the end of 2016 (indeed, one member of the team is working on chord symbols and chord diagrams right now, keeping it going). It is an area that we have made a massive investment in over the past six years.
So it would be helpful to know what specific issues you have, Peter. (And welcome to the forum.)
