We use first initial last name for our logins, which are then used as label on pictures on stage plots. My name wayne Snyder, yields login username as Snyder. We would much prefer the foh to call us by first name, wayne, rather than by Snyder.
To be more clear, use display name rather than username.
Oh, I thought it was using the display name already. I'll put that on my to do list for the next update.
This should be fixed in today's version 4.2.10 release:
