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. Also, the settings of the new replacement amp should be copied to the new item. If I'm trialling an amp with a scooped high gain tone, it makes sense for these dials to be set that way rather than the default 12-noon setting. 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.
