Provide way to recover unsaved work after logout

If the system logs a user out, any unsaved work is lost. If the user has entered a lot of text, this is a high price to pay for, say, an emergency trip to the rest room or being called away by your boss.

I can understand why an autosave might not be viable. For instance, if there is an error on the page, the user wouldn't be able to save anyway.

If would be good if the page after logout contains what was in any forms that were modified at the time of logout.

Steps:
1. User is on a create or edit content page and does a lot of typing.
2. User walks away

Actual result: User loses all work
Expected result: User can copy any text fields for re-pasting into a fresh copy of the form. They can print the state of any checkboxes, radio buttons, or autofill fields for reference when re-filling the form.
