[Option] Mark some key digit drafts by special color (e.g., red) about gauguin HOT 2 OPEN

E.g. a toggle if a pencil is a 'special' one or a normal one?

Yep, it could be enough.

to not make the UI complex

You can place this option ("Pencil mode switcher") to three dots menu.

I first thought, we could display a detail view of the currently selected cell where the user could swap or choose the color/state.

It could be good solution too. But how to implement? If there are more than 1 drafts, long tap wouldn't press any digit but show detail view of cell? Or just bring it as option to three dots menu ("Detailed view of cell")?

Both ways are welcome, I don't mind.

As to Sudoku games... They use bold font for selected digit when clicking on keyboard. Or highlight all such digits on the field when clicking on this digit on keyboard.

Interesting feature, thanks for reporting this!

Do I get it right that one additional color/state would suffice your use case? E.g. a toggle if a pencil is a 'special' one or a normal one?

I am still thinking how to implement that in the UI to not make the UI complex. I first thought, we could display a detail view of the currently selected cell where the user could swap or choose the color/state. I believe this would clutter the cleanness of the UI. The second and current thought: We could put a kind of 'pencil mode switcher' next to the key pad. If activated, a short tap of a number will

• Add a pencil mark if it does not exist with the current mode.
• Switch an existing pencil mark to the current mode if it has the other mode yet.
• Toggle the pencil mark if it currently already exists with the current mode.

I'm still bothered with such a mode... Do you have further ideas of this? Maybe, how do the mentioned other Sudoku games do this?
