LOVE your script and used it all the way through my WK. They should incorporate it into WK base.
The script has 諦 defined as Truth but "greyed out" as n/a, and it's correct that that meaning isn't included in WK.
But the kanji is included in L22 as 諦 Give Up.
It appears again "greyed out" in L27 締 Tighten.

Thanks.
