Not sure if has been asked for before, but I would find a 'history' function useful. I find I might jump around various folders in my local library/rig exchange trying to dial in the right tone, but it's not easy to navigate back to previously auditioned profiles to compare etc.
I think if there was a history page (just like a web browser), this would be really useful to me. If this was too difficult, having the ability to jump between two profiles (current/last) would be a good start.
cheers
