Just bought the programme and am pretty happy except for the following:
No count down on the song playing
No playlist visable, this causes major confusion as you don't know if the song that you have selected has been added or not (it can be seen in the settings menu but this is not avaliable on coin op mode and I don't want it to be avaliable)
Trying to change the currency in the credit table, I am not able to select the number 1, 2, 3 or 4?
Is there a way to address these issues?
Hey megasean
Glad you like it! 
Thanks for your feature suggestions, they will be considdered for a future release.
As for the currency table issue, you have correctly identified a bug and I promise you it will receive my attention, as a workaround you can simply copy & paste those numbers into the currency text field for now.
