Ever get a puzzle you don't want to do? Or start and never finish? Just mark it SKIPPED now...
On the puzzle detail screen, just above the completion date field, you can now mark puzzles SKIPPED when you don't finish them or don't want to do them.
This will remove the "RATE" marker in your collection since you can't always rate a puzzle you haven't completed. And it will not count them as completed in your list of completed puzzles even if you do rate them. Because some times, poor quality or difficulty are the reasons you don't complete a puzzle.
Hope you find this feature useful.
