What's new in ZMHistoryPanel
This change corresponds to the Sketch. We must repeat the cancellation many times even if I cancel the action is recorded only the number when it is repeating the same operation, and want to return to the previous (user and would like it to be) in the state.
You have measures as much as possible so that it can be used naturally in Sketch in this version, but it is a little confused with or reduced action of the list increases or If you have several times undo / redo. Because it is this reason, please do not worry.
