@Grila, thanks so much for your work!!
I can modify the gamewheel like as I wanted.
In the image attached, the result of the theme with modifications I made.
I have simplified elements of the screen, removing some things.
If someone is interested in the changes, for their GPDWIN, I also attach the files that I have modified (only for dark version).
Thank you very much again @Grila
