Rated 4 out of 5 stars

Broken since Thunderbird made the majority of plugins incompatible in a move I will never truly understand. Desperately hoping this and many other plugins my company and I rely upon are soon fixed by their respective devs. Thanks to yshingai for fixing this up once, I hope it's not too hard to fix it up once again - I rely heavily on reliably moving multiple messages from one IMAP account to another.
