Counter example wasn't compile
When I try to run/compile the counter example on the start page with "nimble run", then comes the error "Error: type mismatch: got 'array[0..0, ButtonStyle]' for '[ButtonSuggested]' but expected 'set[ButtonStyle]' ".
The error relates to source line "style = [ButtonSuggested]", when I changed it to "style = {ButtonSuggested}" it compiled and run.
