Option to retain backup on autosaveAutosaving data tables should have an option to rename and retain the existing file as "table.jmp.bak" before saving the new version as "table.jmp". The reason is to prevent autosave unintentionally overwriting a "good" copy of a table with a (mis-)edited version.
An even better option is be able to designate a backup folder where N previous versions of the file can be optionally retained.

Re: Option to retain backup on autosaveActually, on Mac it would be even better to support OS X native system Autosave and Versions functionality (as in e.g. Pages, Numbers, etc.). Don't know if Windows has similar feature.
