- Though we're sure you don't ever make mistakes, we still thought we should improve the Undo and Redo functions...so we did.
- A few users complained about infrequent random crashes. Now, they should happen even less frequently (or hopefully not at all!).
- The Notes function, both for "Possible" and "Impossible" entries, is now even better. Just double tap or triple tap...or select the green or red notepads on the bottom.
