The "d" needs to be adjusted up and left a little bit and it will look a lot better, also the option for dave's idea doesn't seem to work, or at least it doesn't preview.
Also I think it might look good if the options populated from the center point outward, regardless of what they were, I think it would look a bit cleaner than having semi random spaces open, but it wouldn't make it as easy to do a quick glance to see what is allowed and what isn't. Dave's idea solves that though making the label look good regardless.
