A computer program product for using an undo stack to explore past actions and apply new actions to previous states in a data view is provided. The computer program product includes program instructions to detect a change in an application data view. The application then displays an undo stack and stores the data change in the application data view to the undo stack. Upon detecting a selection of the undo stack entry for undo, the application returns the application data view to the state represented by the undo stack entry. The computer program product further includes program instructions to provide a user interface allowing a user to perform operations on undo stack entries. Responsive to the user utilizing the user interface and making selections, the application then adjusts the application data view state based on the performed actions.
