Please add an Edit Undo Last Change

[MikeT]

Hello FXT4 Team,
It would be very much appreciated to offer users the ability to undo the last change, with a history of changes.
For example, accidentally moving an object on the chart should be able to be undone and reset back to its last location.
A change to the color or text should also be able to hit edit-undo, etc.
Thanks,
Mike
