Just started playing around with Beasts and Barbarians Steel Edition. Loving it so far.
I also love the theme. However, the border spacing seems off in FGU. I haven't checked the theme extension in FGC. For example, special abilities overlaps it's button and it appears to me that all buttons should appear in the more olive color of the boarder. Maybe I'm the only one experiencing this. However, I would love to use this theme for other things as well.
