works nice, only slightly annoying part is that you have to restart thunderbird everytime you re-sort accounts, but it works.

do not that it apparently does not appear in the extras submenu of the 3-bar menu but only in the extras part of the header menu, which can be brought up with F10 for quick use if disabled.
after use the menu will disappear again.
