Save Current Revision

A shortcut to save a current revision would be nice. Instead of saving the current revision within the file (though that would be nice too), it would prompt you to rename the revision, then save a copy of the file to your file browser. Instead of dumping it into a random location,  it would wrap the current file, plus the saved revision into a folder. It might also be nice that if you save a current revision, you could send that revision to other users, or to a specific destination within a team or in your file browser.

This is an easy way to prototype interactions; then, instead of creating a new file, you can save those prototypes and delete them from the file after building your finalized assets.

This also serves as a way to freely brainstorm in a file, save an idea, delete the artboard, and continue working.
