I often find myself wanting to know how a task has evolved since it was created. It would be fantastic to be able to "go back in history" to see the task as it was after every edit that was made to it post-creation.

A simple way to implement this would be to provide a History button next to the existing "(i)" (info) button and allow the selection, based on date/time, of the task's moment in time. When selected, all fields would be disabled (uneditable).

Even better would be to provide a Rollback feature that would allow you to roll the task back to the selected point in history.

For the techies out there, I'm think of commands like `git diff`, `git log`, and `git revert`...
