+1 for #'s, even though I'm in the camp that usually either tunes standard or down 1/2 a step, when you're looking at a bubble, needle or strobe it's far easier to see with your peripheral vision whether the note says "D#" or "E" by the fact the letter changes, rather than trying to see whether the little ♭symbol has appeared or not.
To delete the option for viewing ♭at this point would be cruel to the people that want it, the best solution I believe would be a toggle.
P.S. I haven't ran the last 2 updates because of this
Wouldn't you rather look down when you hit your E string and have it read E rather than D? Or See a G when you hit the G string instead of F? And see a A when you hit the A string instead of G? Seems this would be far easier to see than seeing the incorrect string name- forget about the little symbol!
