Would be nice if you could sort your 1000 rigs by guitar.
Then you could put the name of your guitar in the "Pickup type" amp tag (e.g. "Gibson Les Paul P90 Neck"), and have all your guitars together.
Right now, you have to sort of browse through all your rigs and try them all out.
I realize that a rig could be used with several guitars. Maybe there's a better solution than using the amp tag (but it would require more development work).
