Thundersnarl: Provide freeform macro for short folder name (like Inbox)
Several versions ago, there was a value for the 'freeform' notification called %originalfolder, which contained just the name of the folder in it, like "Inbox", or "Banking". The %folder macro gives the long folder name, and looks like "imap://username@mailserver/Folder". Can you make %originalfolder available again?

Yes, I remember that setting. The interface within Thunderbird changed between TB 1 and 2 and the available information did so too.
But I think I can parse the long string by myself and give you access to a shorten one. Planned for next update now
