Is there any way to make the window on the right (that usually displays whatever is in your selected inbox) to show all new e-mails across all accounts? Ive got six e-mail accounts on the go and having to go through all of them is a bit of a pain.

Set up message filter so that all new mail goes to your inbox (or make a "new mail" folder):

 check "match any of the following"



Then set up more rules like this for each address and check "match all of the following":



So that when youve read them they go to the right folder. You could do it by age rather than by read/unread status too.

Im not totally sure itll work cos I cba to test it.
