An autosave feature

An autosave feature should be also there as in many cases the software hangs when working with huge data, or when importing data, or when data being imported is too large and one might want to stop the process but random screen with no content, message, buttons appear in flashes.
An autosave can create copy of the work every lets say 5-10 minutes in the local drive and in case the system or application crashes the auto save file can be opened for review and recovery.
