i like not having to use filter as it’s an extra step. The autocomplete method is what I prefer. So, as it does work this way, fine. And if it works the other way for you, I assume that means it’s not broken so not major concern. Main objective is to add individuals (a feature I didn’t know was added, as I had stories off for a long time).
As for “A” over “I” – I’ve always used right from the very start. “I” isn’t good as it is too close to the number 1 and easily mistaken for that. Even for my Royals, I changed to “Q”.
