What's new in PerPuzzle
Keyboard commands for rotating the Wrap Slide tableau and for swapping the Wrap Slide frames have been added. One may now rotate the tableau 90 deg with Command C. One may now swap the upper and lower frames with the Up/Down arrow keys and swap the right and left frames with the Left/Right arrow keys.
A minor error in the Wrap Slide help file has been corrected.
