You are correct that this is a 7yr old request for the most basic of functionality.
I am also struggling to find a way to select multiple entries and delete them from the list of my saved sites, I have to enter into each entry individually and then click delete/confirm which would take hours to go through my passwords with this mess.
It’s crazy they are asking money for this product when it lacks the most basic in password management functionality, definitely look elsewhere for your password management requirements as this shows their attitude towards the end user.
