I have created a FB group, called CIRCLE BEYOND KNOTTER . It has the original and my expanded version of knotter as zip files, so all the coded ( Json and UI ) are complete and ready to run on Win 10.
The group is private this mo, while i upload files, pics, and docs.
Mattia knows i did explore other ways of sharing, but soon realised the method was going to be too complicated for many folks.
I welcome dedicated fans of knotter, including Mattia, to visit , and or request to join.
I do need another Admin, in case ( i am getting old now ) i am no longer. I just wanted to save what i made possible so anyone can use it, and if you understand Json and UI, how i made the additions to Star and Circle. FB means the group will remain functional a long time after me.

once i am happy as much as i can add is added, i think it can go public. I actively use META AI to help in making it secure.
