Knowledge Book in sets of 3's?

[elbogg]

Hi there,

I was wondering if anyone could set up a Knowledge Book that works in multiples of 3's, instead of 4's? I was thinking of something maybe 4 wide by 3 high, about 3/4 size and as much dead space as possible removed. The only time I really use the Knowledge Book is when I'm crafting, and since the crafting skills come in sets of 3 it would cut down on dead space and empty slots if I could stick them in there in 3's.

Thanks!
