Description Jan 2012-02-16 10:14:10 UTC 
Version:           0.5 (using KDE 4.8.0) 
OS:                Linux

it would be great, if the little numbers could be hidden automatically, if the user inserts the number on an other field in the same big field.
Maybe it can be displayed again if the user deletes the number again.

Reproducible: Didn't try

Steps to Reproduce:
insert some little numbers in the fields
insert one of the used numbers on one of the fields

Actual Results:  
the little numbers are still all displayed

Expected Results:  
the used number should be hidden from the list of little numbers

OS: Linux (x86_64) release 3.0.0-16-generic
Compiler: gcc

I use a similar feature in Andoku 2 (for Android), and I love it. Just for the record: Andoku categorizes this feature as optional hinting.

First problem, Jan, if you have KDE 4.8.0, you should have KSudoku 1.0, which has an improved generator/solver. Maybe you need to install the latest KDE Games release.

That will not provide the feature you are asking for, but I will have a look at providing it in the KDE 4.9 release. I like it, too.

Re "optional hinting", I am not sure what that would mean, but I think KSudoku should just auto-delete the markers (little numbers) you yourself have entered, when they become no longer relevant. The auto-delete feature would be an optional KSudoku setting.

I seem to have seen some Sudoku apps that can automatically fill each cell with little numbers for all currently-valid values of that cell, but I think that is providing too much help.
