Very nice work so far - seriously one of my all time favorites - received an error message right away but did /rl and it hasn't popped up since. 2 features I would love to see added are the ability to fade out so it is essentially hidden until moused over and the ability to have a separate bar so I can have one bar with buttons going left and a different bar with buttons going right. Thank you so much for this wonderful addon and again great work !
edit: Oh and Right click self cast!
edit2: Having main buttons disappear after logging out and back in - also changes position from last placement if master scale has been used.
