Autocompleted rows and columns should behave a bit more consistently now, thanks to a suggested change by Bumbino!
Hints weren't hint-y enough! Now a second press will reveal a cell. Thank you for the suggestion Maple, srps, and Zoro!
The cell cursor was a bit difficult to see on some screens, so additional options were added for colors and crosshairs in the play board. Thanks for the suggestion Pudd!
