One big enhancement I would love in the tuner would be the possibility to define alternate tunings (for instance drop B, ie define appropriate tuning per string and not provide only the chromatic value) and even more important for me, the possibility to define sweetened tuning, i.e. my 6th string is a E minus xx cents, my 5th string a A minus yy cents, etc. as it is possible in Peterson and Sonic Research tuners for instance.
Definitely, then I would remove my tuner from my pedal board !!!
