I must be getting old but my ui skills seem to be lacking me. I'm looking for a mod of Aya's spell bookwindow (to be used with her 8.51 ui), basically changing the window from 2 columns of 8 back to the more default 4 columns.
i.e a change from this (where letters are the spells in book)
a----i----
b----j----
c----k----
d----l----
e----m----
f----n----
g----o----
h----p----
to this
a----e----i----m----
b----f----j----n----
c----g----k----o----
d----h----l----p----
