Hi, after the update the numbers with correct lines are no longer greyed out, they always stay black - is this intended?

is it possible to integrate a second line color to exclude possibilities? Or is there a UNDO-function?

Any way to pick the old font instead of the new one? It's so thick it's hard to read the numbers.

Can't relax and concentrate on the puzzle with that distraction.

Due to a recent update, my game progress has been reset. (Sad that I can no longer access the endgame map ) It is possible to advance progress to any map by adjusting the Settings.json, correct? If it is not against the creator's policy, I would like to see the method disclosed....
