Autosaving
If you haven't saved your document recently ("File → Save"), Sandvox will autosave any changes. The autosave function in Sandvox saves a copy of your Sandvox document alongside your real document, titled something like "My Document (Autosaved).sandvox". This means that should something happen like your computer losing power, you should only lose a few seconds' work. When Sandvox is relaunched, the autosaved copy of your document will open, and you can save it if desired.
The time interval for autosaving can be adjusting in the Preferences.
