When I want to trial different amps or cabs in a chain, I would like to drag an amp or cabinet on top of an existing amp or cab and have the underlying cab or amp REPLACED by the new item, with the settings of the replaced item copied to the new item. If I'm trialling an amp with a scooped high gain tone, it's likely that I want to keep the high gain scooped settings, so the 12-noon positions of the new amp's controls isn't helpful. As it stands, I need to delete the old item and change the settings in the new item to reflect the desired tone. I think this will make Tonelib even better. Thanks for a great product.
