Thank you for your thought good feature suggestions! We want to make it a good tool for learners.
We want to realize it in the not too distant future.
Thanks, that would be great!
A part of this function was implemented in ver.1.2.6. :)
Regarding the chord display in the proposed parenthesis, I did not implement it this time because there may be multiple chord names and the specification becomes complicated.
Thank you!
