Hive mind who uses Thunderbird: The latest release, 153, has removed the ability to bulk subscribe to IMAP folders. You have to click the checkboxes one by one. This is a UX disaster, as our new employees have to subscribe to hundreds of existing folders. Surely there's a better way?
(In particular, the click-on-first, shift-click-on-last trick now no longer works.)
@futzle for your imap server use a subscriptions file (like courier IMAP does) and does Thunderbird honour it?
