Ah, okay!
I’m still a bit confused as to how these two requests are different, since Option: open last used vault or open vault selector is asking for the ability to choose opening to the vault selector instead of re-opening the last used vault (which was already the default at the time). The use case given was for people who didn’t want to open the same vault every time.
But either way, Pick a vault on app launch describes what I’m looking for. Thank you!
