It would be nice to have a panning control added to the existing metronome config. There's a risk of click bleed when musicians prefer to monitor with only one headphone over their ears. Rendering and panning is an option, but not if the musician is still dialing-in their desired tempo. (Not everyone cares for ear-bud style headphones, especially when singing).
Also, it would be nice to have the option to bring up a resizable window with a graphic metronome on screen. S1 could give options to have only graphic, graphic plus (pannable) sound, or only sound. Presonus could even offer multiple appearance variations (and/or instructions on how to DIY your own graphic).
