When using the Markup or Colouring tools I find the candidates very hard to read. Could you please make them black and bold? This applies both to the SudoCue and Clueless Helper programs.
I sometimes like to make printouts of particularly difficult puzzles to take with me on public transport or just to leave on the kitchen table to look at later. I tried the print function in SudoCue once. I then copied the puzzle to Simple Sudoku, made the printout again and had no problem reading the candidates.
While I think making the candidates easier to read on the monitor should be a higher priority, (I can continue to use SS the odd time I want a printout) it would be nice if you could make them legible on printouts too.
Many thanks for your excellent software and the hours of entertainment I have had since I discovered your wonderful site.
