On: Google Design

I've had the opposite experience. To delete all emails from a given contact....search for from:contact, select all, delete. Idk how that could be more intuitive?

More intuitive would be not having to know the command. Is it still "from" if my gmail is set to German or French?

Anyway, I do think google solved this in to ways: type contact and from:contact is suggested

If you rest the curser over a contact name, a box with an option to see all conversation appear.
