This button's code in gdscript 4 uses selector modes- only one possible at a time. It is attached to the 9 children small buttons of the main button.
There is singleton code that is just an array with each row being a string descriptor, a color, and three booleans- first sets whether to checked by Sudoku rules, second sets whether to set a the main number and hide all small button for that main button, the last removes same numbers in column/row/square as main number.
There should some way to simplify the many modes that this special Sudoku trial buttons uses.
Do you have any suggestions on how to clean this up a bit?
