I would like to see an option to have all pencilmarks filled in on startup. I like to eliminate pencilmarks as numbers are played as opposed to filling them in as they are not played

I agree completely with this request. Having an option to automatically insert pencil marks enables a user to avoid "grunt work" without negating the logical solution challenges. By contrast, I would not want to automatically delete pencil marks whenever a large number was entered.

I also agree it would make solving the puzzles faster and easier, but whenever I foul-up a puzzle, it's because I missed inserting a pencil mark. I'm putting a lot of effort into being more diligent about this and not get so out-of-control.

I've been playing SudokuXP lately (http://www.extendedreality.com) which has an automarking feature, and it's pretty good... it basically fills up all of the "obvious" marks, without solving the entire puzzle for you.

The great thing is that after all the initial pencil marks are put in place, you can either leave automarking on or else turn it off. If you leave it on, then placing a number in a cell automatically removes marks for you. But if you turn it off, then you can play a regular game where you have to remove marks manually (so in a sense, the gruntwork of placing the initial marks is done for you, but the rest is up to you).

Give it a try!
