When testing new loaded rigs for live-application, I try them out in our rehearsal-room via our P.A.
There I've got no PC (for RigManager). So it would be very useful to find a softknob in Browser Mode, where I can delete useless rigs at once. It is rather circumstantial to delete rigs via "delete non favourites". This affords to make them all to favourites at first and then to untag them.
I would highly appreciate to find a soft knob "delete rig" in Browser Mode (via Rig-Button or else)
