System-wide Undo Support
See also: Non-destructive editingThe ability to undo across different programs and time frames is absolutely necessary in this type of system because human error is the only cause of system failures. Humans innately have the mind to do so. Not having undo support also limits testing aspects of a production system because it doesn’t allow for trial and error.
System-wide undo support should cover all aspects of the system. This includes hardware and software upgrades, configuration as well as application management. There are obviously limits to what can be undone, and these limits are currently being explored, tested and rated based on their tradeoffs.

Famous quotes containing the words undo and/or support:
“Let thy song be love. This love will undo us all.”
—William Shakespeare (1564–1616)
“There are so many intellectual and moral angels battling for rationalism, good citizenship, and pure spirituality; so many and such eminent ones, so very vocal and authoritative! The poor devil in man needs all the support and advocacy he can get. The artist is his natural champion. When an artist deserts to the side of the angels, it is the most odious of treasons.”
—Aldous Huxley (1894–1963)
