Currently, since B and N are next to each other on a QWERTY keyboard, there is a good chance that a user intending to restore the recent best could restore the very best solution by mistake, and thus wipe out the recent best if it's off the undo graph (due to being more than 100 moves from the most recent state, etc.) Adding a confirmation dialog similar to that for resetting the puzzle would be useful for avoiding this problem…
