Undo/Redo in a product-painting-webapp shall be tuned by animation. If the user click undo/redo i have both painting's, the actual and the to-be-actual painting.
One painting is a multi-page painting area (like a book for left/right area).
Ok, i think about a animation either
- transparent-appear shrink/grow
- or left-swing for undo and right-swing for redo
Any other suggestions?
