Nope no such thing as too late smile
I added the stat "Memory Slots" under the "Stats" block which shows that and also added a method of selecting valid talents under its own tab.

I really struggled with how vitality is calculated and never quite got to the bottom of that one unfortunately smirk
Considering level with Constitution / Lone Wolf / Picture of Health / Sturdy I was never able to get that one to reliably give correct answers

I've currently moved over to spending most of my time on a "Fate Core" character creator here
Google Sign in won't work there though as it needs to be hosted on a 'proper' domain xP
But I'd like to go back and finish my divinity one, at least when I have the patience or someone has the answer to how vitality works :')
