I use an expression pedal connected to the Remote for a dedicated volume pedal. I will often use it to kill my sound between songs or during sections where I need to be quiet, but the tuner display that automatically pops up is very annoying. This was a useful feature before I had the Remote but now it's a hindrance as I'd prefer to see my preset layouts, effects layouts, etc. without having to dismiss the tuner with an additional unnecessary button tap. I'd like an option to disable the automatic tuner pop-up, the dedicated tuner button on the Remote serves me just fine.
As for the cents readout, it was already shown earlier this year in NAMM videos of the Remote, seems like a very simple addition that would be very beneficial.
