Hello,
Thank you again for your help.
I adjusted the gap between the last two frequencies as you suggested.
And I managed to implement the sliders that multiply or divide the edge refinement value using the micro, fine, etc. sliders, all of which are collapsible.
The latest version is on the drive and GitHub is synchronized.

Have a nice day,
Christian
