OK, so I wasn't planning on it, but I did it anyway:
v1.6 has cultural base chances, picks them up from the first character entered in the Culture box (B, C, N, P). Choices are highlighted in light blue, with pop-up annotations indicating how many choices there are to make, and what combat styles are available. I had to move the Skills across so they aren't in the same columns as the other stats, because the column widths work better that way. It looks a little odd but I think it's slightly better like this.
Don't bother asking for Professions! Cultures is only possible because there are only 4 of them, I'm not adding 30 columns for theose! Hm, 30 columns, maybe that isn't too many...
*Update*: Nearly right - but some of the minor informational calculations above the skills aren't working correctly. Ignore the numbers below the "X"es for now...
*Update*: Fixed. The values under the "X" go yellow as you add in optional values, and go green when the numbers of choices and the total of the skill points all add up, and go red if you go over.
