Hi, Is there a way to run a command every time a message gets tagged? I would like to keep in sync tags and folder names. The problem is that it requires a full scan of the notmuch db, which is slow. If I was running this script only on messages that got retagged since like run of my script it would be much faster. Unfortunately I don't find a way to mark/save these messages in a notmuch hook. I found an old thread from 2012, where somebody mentionned they implemented a post-tag hook. Was this ever integrated? Cheers, Christophe-Marie
