I will make a official forum thread about chocolate bar once multiple bar support is finished, its almost done but I have very little time at the moment-.-
I'd go ahead and start your forum post now to get feedback. I think a lot of people would like to use it even with it being only a single bar simply because you added the center alignment. I for one am very happy with how simple it is to set up.
I've noticed that after setting up my chocolate bar for my main, the settings are not carrying over to my other characters, even when I try to copy the profile from the 'finished' character to the others.
