If I decide I’ve made a mistake entering the operation for a no-op puzzle, I haven’t found a way to erase my mistake and set the cell back to its original state. Is there a way to do that?

good point

when using the keyboard, you can erase the operator by pressing Shift + left arrow key until it disappears
(you go "past the +" again),
but there is no button for it, and there probably should be.

will see what I can do

There should be a "clear operator" button now for the no-op puzzles
