Since I am trying to beat my previous times, when I enter pencilmarks, I am just happy to hit the cell I want. I would still like the entry to be in a certain position, even though I do not exactly hit a particular spot of the cell.
The checkmarks should appears in the following positions in a cell:
1 2 3
4 5 6
7 8 9
The present option choices almost give this to me, but not quite.
This is how I put the pencilmark numbers while doing it by hand. It really helps because of my not-so-good eyesight. Under the present choices, I have to use the automatic re-order and the 6's and 8's and 9's sort of look the same. If the 6, and 8, and 9 had specific locations in a cell, then they would be easier for me to solve. The pencilmarks are spreadout completely throughout the cell.
This would not make solving the puzzles easier, but it would depend less on my eyesight, which should not be a factor anyway.
Being a retired programmer, I know this is a very large request, but it would really be appreciated if this modification could be made.
