I have just upgraded to Fedora 22 which includes the new Gnome Sudoku. Current version is 3.16.0
While the overall new look is an improvement, both the lower notes field and its associated show-all-numbers was removed and the track-changes functionality was removed. Some searching found developer discussions from the time of the changes that stated that show-all-numbers was basically a cheat that legitimate users would not use. This was followed by a request for possible valid uses.
While I agree that just turning on show-all-numbers and then blindly chopping away at the puzzle is not very edifying, my normal use of show-all-numbers is to cross check my counting at the end of all my analysis which sometimes has human mistakes. Having my count in the upper field of each box and the show-all-possible-numbers in the lower notes field was a useful and much-missed capability that should be restored. I miss it.
Then, once I have exhausted my toolbox of solution techniques, there remain a class of puzzles where there are two possible solutions and the only technique is to try one until either it proves correct or produces a conflict, at which point the track-changes "revert" capability allows one to go complete the puzzle with the correct path.
Some sudoku wizards may look down on my limited capability and say that I should just learn more sophisticated solution techniques, and I do try to improve my techniques. However as it now stands, Many puzzles are unplayable for me without the track-changes and show-all-numbers functionality. I would appreciate it if they could be restored to the game.
