As you see the block 4 in the main window, all operations are listed as pending for preview. You can click Undo to cancel the unwanted operation or click Redo to recover the cancelled operations. The real disk partitions won't be changed until you click Apply button to confirm.

2. Cancel-at-well technology

If you confirmed and started the changes, other server partition software don't allow cancelling the ongoing operations from the beginning or over 50% progress even if you did something wrong.
