I'm not sure if this is the right forum for this, but it looks like there's something weird going on with the layout in the Skills chapter in the beta. Some skill descriptions have normal case in their headers, while some have all uppercase, and I don't see any pattern or meaning behind the difference in the two. Even stranger, Heal has normal case in the skill name in the header, but then the parenthetical is uppercase.
It's a little thing, yeah, but I figured you'd want to know tiny layout problems like this as much as tiny rules problems that might pop up.
