With the mailbox having limited space and the read ones having to be deleted it’s VERY tedious and my arm honestly hurts from having to move forth and back between delete and clicking a mail (yes I am seeing a doctor for it and getting some training for it already).
EDIT: Even without arm pains this would be a huge QoL and help all players, without taking too much devtime (I’m a dev so I know that’s a bold claim to make)
Sorting it by upopened first would help with this issue, or (a setting?) deleting the emails after grabbing all attachments could also help but this is probably harder to implement.
