Yeah, me too. The Amiga had a good idea with its Preferences programs (i.e. settings or options) - a "Use" button, which only saves to memory, separate from the "Save" button, which also saves to disk. So even if you make a mess of it, just reboot. Of course, in those days we were used to rebooting often, so that wasn't an issue. But if the idea had caught on, then by now we'd probably also have a "Revert" option that copies from disk to memory and activates it.
