Grabs all parameter settings into the input area above this button. Then you may select all text in this input area, copy it into clipboard and save on your disk by means of any text editor.
Unlike "Grab", this button appends the grabbed settings to the end of the text above. You may click this button after several pack stages (performed with different settings). Then, the full pack scenario will be accumulated in the text area. If you will restore such multi-stage scenario, then the single click on "Apply" or "Execute" button will build all stages of the pack in a batch.
You may insert the text, saved by "Grab" button, into the input area above and click "Restore" button. Then all saved settings will be restored. Following pressing "Execute" will build the same pack as was built by the saved setting.
