After playing this game for year and year a thing that still drive me nuts that should be able to be fixed is the mailbox. I would like to see a easier way to empty the mailbox. One option that would be make everything easier is to select if you want mail for favor rewards. For first time these were helpful but after 10 years they don't really serve a purpose.
Just some basic quality of life improvement would make a huge difference. Theres nothing more annoying that going to AH and getting the message your mailbox is full.
