Hi,
Would it be possible to have an undo or confirm button (rather than having to change settings manually) please, and
Is there a way to auto-highlight incomplete sets so we do not have to manually check each set in turn based when it might be hours between turns?
Thanks.

Having played on both sides of the world, the only times I have ever won have been in Europe, even on scrappy internet compared to my high speed one at home in Aus. I am not a great player by any means, but it definitely makes a difference.

I'm missing the following ones and about to give up hope. I would love a walkthrough after to better prepare next year please? "8": false, "9": false, "12": false, "15": false, "17": false, "19": false
