Great thing! I'd like to report one bug, though:
I'm using the unified inbox feature, and when I install extra folder columns on thunderbird 3.1, all my Inboxes are named "Inbox", which is quite confusing ... without e.c.f. installed, they are named after the account they belong to.

This review is for a previous version of the add-on (0.4).
