Workflow audit/history/change log

### Feature Idea

I've not been able to find this feature if it already exists, but it would be nice to have an audit log of every change to every workflow that you can scroll through to review or revert changes.

I'd imagine adding a button to the workflow tools (i.e. Select Mode button) that brings up the audit window / panel and lists changes made to that specific workflow. Each time the Queue button is pressed, if the workflow has changes an new entry will be added to the audit history.

A separate but related feature would be an "auto-save" feature that auto saves a workflow (and it's audit history) every time you queue it.
