Sample full animation effect created by this plug-in:  Cropped sample:  This plug-in will rotate all your linked layers.  Linked frame speed, is a string of numbers (comma separated) that tell the plug-in how to rotate the linked frames. In example shown above, -1,1,-2,3 will tell it to rotate first linked layer at negative full speed (full revolution) rotate 2nd linked layer at full speed rotate 3rd linked layer at negative double speed rotate 4th linked layer at 3x speed. code below. #!/usr/bin/env python
# rotate-linked-animation.py

# Rel 1: Initial release
# Rel 2: Leave the visibility unchanged of linked layers, added "Change Opacity" and "Move Layers" toggles as suggested by PixLab http://gimpchat.com/viewtopic.php?p=284716#p284716
