This add-on is what makes Thunderbird amazing. I order my inboxes based on this (1_High, 2_Med, 3_Low, 5_Calls, etc) and can sort a hundred emails in a matter of minutes before starting to tackle inboxes one at a time. I live and breathe email running my software company. Dying to have it on the latest TBird again.
