Xara quotes in http://www.xara.com/uk/designer-pro/features/:This is in direct conflict to saving your work frequently.Infinite Undo / Redo
Being able to change what you have done is vital in a graphics package. Xara Designer Pro allows unlimited undo, making experimentation easy.
No number of backups afford this feature once you have saved the design file. All you have is a design file snapshot with no memory of how it got to where it is.
The only way I have gotten around this is to keep the design file open (always) and clone the latest backup to the name closest to the design file name so I always have the latest version and a true "Infinite Undo" - subject to Terms and Conditions and the amount of memory you have available...
Saving this Undo/Redo information is trivial and minimal in extent.
